Tech Help Q & A

If the lifting points are Accessible, pickup diagonally from the front Left or Right Front Cylinder Head to the Rear Left or Right Cylinder Head. Otherwise from exhaust port holes in the cylinder Heads. Use a high grade Bolt that does not stick out more than a ½ inch otherwise it will bend up and snap off from the chain or cable causing the engine to fall . USE a heavy duty chain or cable long enough to prevent scratching the Valve covers or damaging the Air Cleaner. Never stand under an engine that is suspended in the air, always ask yourself if it falls where will I be.

We normally suggest using a high Grade SAE 10W/30 Motor oil along with a ½ pint of a good quality zinc break in oil. After 2 oil changes if you would like to go with a synthetic or blended version then this is O.K. Do an initial oil change after 500 Miles then just every 3000 miles from there. Note on the first oil change your oil will look blacker than normal this is because when we assemble the engine we use a heavy duty Graphite on all Moving parts. Many people will ask how many quarts of oil does my engine hold. We have to tell you that every engine is a little different because we install the oil pan that is Made for the application, many will only take 4 quarts and some as many as 8 quarts. Here is how we want you to do it, on initial oil and filter change, first fill the new oil filter to the top, Then install 3 quarts of oil in the engine, then count how many additional quarts does it take to reach the full mark on the Dipstick, caution do not overfill.

Engine Factory will normally do the break in of the camshaft on our Turnkey engines.  Upon taking your vehicle on the road for the first time stagger the throttle from 30 to 50 MPH several times to get the Piston Rings seated properly. Keep the RPMs under 4000 RPMs for the first 1000 miles.  

Keep them under 5800 RPMs.  The power starts to drop above this anyway in most Street Engines. You will have all the power you’ll ever need below this level anyway. Going beyond this definitely increases your chances of damaging internal Parts.

When filling cooling system, top off Radiator with 50/50 Mixture of Antifreeze and Water with engine cold. After engine is started check coolant Level after engine  reaches 160 F. Top off as necessary. Always use caution around hot coolant, Always use a temperature gauge not an idiot light. After the engine reaches 180 degrees shut it down and let the engine cool down then slowly remove the radiator cap start the engine and top off.

This can be a huge list but one of the most important ones to mention would be the Radiator. Use a brand new Aluminum or 3 to 4 core Radiator to keep your replacement engine cool. Some other items would include Engine and Transmission Mounts, Clutch, Torque converter, Fan, belts, hoses, U-Joints, pulleys, hoses and clamps, fuel lines, sensors etc.  Reference our installation tips list along with and review each tag on the engine. If you don’t feel comfortable to take this on then contact a qualified mechanic. Early model vehicles with drum brakes should be converted to disc brakes when installing a high performance engine. Most serpentine system require using an electric Fan  the Flex lite 180 series puts out 3300 cfm and will keep your engine nice and cool.

GM HEI wiring terminals

Here are the part Numbers you can order from   www.summitracing.com   although most auto parts store will also have them many different brands >>>> be sure to tell the guys the Power lead must be hooked up to the Ignition terminal so that the distributor has 12 volts with the key on and no voltage with the key off. Never hook up to the same wire that powers an electric fan or the automatic choke

Chevy Flywheels and starters compatibility

flywheel-starter-compatibility
Flywheel and starter on the left is 153 tooth and the compatible starter has bolt pattern straight across from each other; this flywheel uses a 10.5 inch Clutch; Starter can be ordered from www.summitracing.com  Search Item PowerMaster PWM-3631

Flywheel and starter on the right is 168 tooth and the compatible starter has the bolts staggered across from each other; this flywheel uses a 11 inch clutch. Starter can be ordered from www.summitracing.com Search Item PowerMaster PWM-3510

See important technical item below.

The starter bolts are special and also the engine block is special where the starter bolts seat >>> When you get your starter off always look at how the engine block has the starter bolt holes recessed up in the block again the threads in the block should be recessed up in the block about 3/8 of an engine this allows the shoulder that is built on the starter bolts to fit up in that recess precisely that is what gives the bolts the strength and keeps everything in perfect alignment.

 

Chevy flexplate and starter compatibility: both have Balance weights 86-96  when they bolt up be sure weight goes to the front of the engine.

Also, years that have these combos please consider that over the years Chevy engines have been transplanted into just about every combination out there.  A quick way to tell what size flywheel you have is to look closely at starter bolt configuration and compare to my illustrations.

If a customer’s torque converter does not bolt up to flexplate then they will need the torque converter that has multiple bolt holes.

The starter bolts are special and also the engine block is special where the starter bolts seat >>> When you get your starter off always look at how the engine block has the starter bolt holes recessed up in the block again the threads in the block should be recessed up in the block about 3/8 of an engine this allows the shoulder that is built on the starter bolts to fit up in that recess precisely that is what gives the bolts the strength and keeps everything in perfect alignment.

On some engines Like Corvettes and Cobras The customer fills his cooling system and thinks his engine is full it is not; that is because the radiator fill neck sits lower than the Thermostat housing, Coolant does not run up hill which means the upper portion of your intake system is not completely full and that is where your Temperature sender sits. I recommend the Moroso upper radiator hose fill Part Number 63730

Now another reason if your engine temperature is higher than normal; If you have installed a late model Serpentine Belt system that is driven by a single belt, You must be aware that those system use reverse turn water pumps. Here is where most people go wrong they put on a fan and fan clutch that is for a standard rotation pump, this means your Fan is now turning the wrong way, easiest way to resolve this issue is to use an electric fan we recommend the Flex lite 180 series they deliver 3300 Cfm’s of air flow and will keep your engine cool.

Very important to follow these instructions:
Distributor and Electric Choke positive terminals must be hooked up to separate 12 volt key controlled (on and off with key )  If you use an electric fan it must be hooked up to a separate circuit otherwise it can burn out the ignition module in the distributor. Here is why if you shut the vehicle off and the fan is still spinning the fan acts like a generator and sends back a voltage spike that instantly  burns out the Ignition Module in the distributor.

Also be sure to have a heavy duty 4 Gauge Ground cable going from the engine block to the vehicle frame otherwise you will constantly be adding water to your battery and your alternator will be spiking voltage at 18 volts.

Most auto parts stores have a simple piece that plugs into your fuse panel and adds 4 separate key controlled circuits that plugs into the accessory circuit.

Over the years One question that get asked very often How do I know if I have installed my automatic Trans Torque converter Properly?

Now let me say this We are engine Builders Not Transmission builders But over the Years of building our own Cars we learned the right way and the wrong way about installing torque converters on a freshly Built Transmissions, we have found the following Method has always worked well for us.

The first thing Be sure when you order the Torque Converter tell the trans person what Camshaft  and Horsepower you have. Are you building a cruiser or Hot street machine because this will determine what stall speed you want for the converter, Most cruisers will stay with a 2,000 stall speed, 400 HP around 2,500, 500 HP & Up will go with 2800 Stall Speed  of course if you know your rear end ratio also give that to Transmission shop.

Now when you order your torque converter best to order the converter that has multiple bolt holes where the converter mounts to the engine flexplate, most performance converters normally have the multiple bolt holes.

Ok now when you’re ready to put the converter onto the Trans we always recommend take a look down in the converter and see if you see any trans fluid pour in 1 quart It is best so that it has some lubrication and helps to pick up the pressure faster, now look at the front seal if it looks ok then spread a little of trans fluid on the converter shaft just so the seal has instant lubrication so you don’t burn the seal lips. Now pick up the converter and slide over the trans splined shafts, slowly push into the Transmission and keep rotating the converter you will see it drop back a little that shows it went onto the 1st set of splines now keep turning and pushing back it will then drop back one more time and that means you have dropped back on the second set of splines and have engaged into the Transmission front pump give the converter a spin there should be a nice smooth spin no binding or noise.

Now it is time to mate the Transmission to the Back of your engine, first make sure the Pins that the Transmission line up on don’t have any paint on them, also make sure that the Transmission alignment holes are nice and clean.  Now take a couple of Extra 3 inch long bolts and cut the heads off, just thread them into the back of the engine by hand about 3 full turns this will help you to easily slide the trans onto the back of the engine, now have your trans bolts ready to install thread them in by hand and use a hand ratchet, you will now see that the face of the trans and the block are mated together. Now very important reach under and try to spin the torque converter, If you can that means success you now know the Torque converter is installed in the trans correctly, so now is the time to install your converter to flexplate Bolts, you should have about ¼ of an inch space between converter and flexplate that’s perfect, now pull the converter forward until it lines up flush with the flexplate, now install your torque converter bolts nuts and lock washers and torque up everything, now Ford converter use the same procedure except the ford converter have studs that you have to spin  the converter to line up the holes into the flexplate.  Always be sure you use a new Trans cooler.

Clean Off the timing pointer.

Clean off the Balancer we usually mark 15 and 34 degrees on it.

Warm up engine

Hook up your timing light.

Pull vacuum line off the distributor vacuum advance.

Bring RPM’s up to 3,000 and hold steady.

The Mark on your timing pointer should line up with the 34 degree mark on the Balancer.

Adjust if necessary.

Hook up the vacuum advance hose, timing will be correct at all rpm’s

We hook up the vacuum advance this way because it helps to give a much better throttle

Response and a better idle.

Your Holley Sniper engine has been live run and properly set up, only use below if you think someone has changed the settings.

(1) Follow prompts on initial set up screen usually set idle setting around 1020 rpm. on menu screen.

(2) Start up engine and let idle until coolant temperature must reach 160 F. Set idle screw to 1000 rpm if needed for setting timing.

(3) Then set your distributor timing so at 3000 rpm with vacuum advance hose disconnected from distributor. Set timing to 34 degrees BTDC. Then hook the vacuum advance hose back into distributor.

(4) Now shut engine off & turn throttle body idle screw clockwise one full turn .

(5) Then start engine up idle will be at 2000 rpm.

(6) Then  very slowly turn idle screw counterclockwise to the left. Until on the menu screen the IAC % reading is reading between 2% & 5% .

Then let engine idle for a minute so computer can learn.

(7) Then restart engine and engine idle should Level off to the setting you set it at from step one. Which was about 1020 Rpm. That's it.

The image above shows where you hook up power brakes.

you will need these fittings Edelbrock Number 8096 and Edelman # 846260  Order both from

www.summitracing.com   There are many other places on the Carb, look at 2nd attachment.

to hook up a vacuum hose going down to the Transmission it needs Vacuum all the time.

These items should be left to a certified mechanic.

Your Electronic small body Distributor  will have 3 wires coming out of it:
- Red goes to Positive on the Coil
- Orange wire goes to Negative on the Coil
- Black goes to Ground.

You need 12 Volts Coming from your Ignition switch, both Crank and run position, that works on and off with the Key.

Also, a word of warning, never hook up an electric fan on the same wire that powers your distributor, it must be on a separate circuit coming from your fuse box. Here is what can happen if you shut off the engine and fan is still spinning it acts like a generator and sends a voltage spike back to your Distributor and it can burn out the module in the distributor giving you a no spark condition.

Top off Oil with a good quality Brand SAE 10W 30 oil  fill until the dip stick says full, use a  good brand Green Antifreeze a 50/50 Mix Zerex, Prestone etc.,  Disconnect the coil wire,  Remove the Air Cleaner, Open the Throttle and spray down In the CARB a 5 second shot of WD 40 then spin the engine over for 20 seconds, let it sit for 5 minutes,  then spray in another 5 second shot of WD, spin the engine over again, for about 20 seconds this time keep an eye on the oil pressure you should see it starting to come up. Now put coil wire back in,  and install the air cleaner be sure there is fresh fuel in the gas tank, start the engine it should fire up  run it on fast idle about 2,000 rpms  IMPORTANT Monitor the oil pressure it should come up immediately, if it doesn’t stop engine.  I am sure if it had oil pressure when it was stored away no reason it wouldn’t have it now, top off cooling system and monitor temp and then road test.

Info before you switch from a Carb to an EFI engine system. Here is the problem YOUR Camshaft may not EFI compatible, yes switching over to EFI sounds Good,  but with Camshaft that is in your engine you will find it difficult to Tune, In other words you would have a hard time to get the engine to run smooth, EFI systems require a camshaft that has a 114 lobe separation yours is most likely a 110,  So unless you Plan to change the Camshaft You may want to rethink that plan,  if you have a good Mechanic it can be done but the key words here are  ( GOOD MECHANIC )

Regards,

Bruce

In about 90 % of the cases it usually comes down to two issues, It can be the choke is Binding or it has not been wired correctly, the electric choke must have 12 volts whenever the engine is running. Start with the engine cold overnight, push the gas pedal to half throttle to set the choke  it should snap shut, now let’s remove the air cleaner Lid only, look to see that choke butterfly is now closed, check to see if it is opening and closing smoothly by pushing the top butterfly open and closed with your finger it should open and close easily without any binding,  sometimes we have to use a plastic spacer for the Air cleaner  to clear the Distributor they are very touchy  if they are not put back on correctly they will bind up the choke mechanism, now start the Vehicle  it should go on fast idle and the choke will start to open fully after about 10 minutes of running, If not have a certified mechanic check and repair as necessary.

Another more serious problem is you Have picked up a piece of dirt Or rust in the Carburetor Needle and seats which cause the carb to dump raw gas into the intake,   if you have an old fuel tank 10 Years or older by now over the years the tank has collected small amounts of water which turns to rust, water is heavier than fuel so the water and rust settles to the bottom of the tank and is pumped into your Carb or fuel injectors causing a Major flooding problem. If that is the case you will have to have a professional remove the carb and have the needle and seats cleaned by a professional Carb person, or in the case of fuel injectors those would have to be replaced. Engine Factory always recommends replacing a gas tank that is 10 years or older, go online Holley has a good selection of new fuel Tanks

The EFI system we will be

Using is the Holley Sniper #  550-511  we will have the hand held all dialed in to use this system. Note Engine Factory does not supply  ( fuel tanks or in tank pumps ) you can purchase direct from www.holley.com    or    www.summitracing.com 

This in-tank fuel pump module is a high-pressure unit that flows 255 liters per hour (LPH) and is capable of supporting electronic fuel injection (EFI) engines producing up to 550 horsepower • A pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application is included • This module also features a Hydra Mat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates Fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank! This 1964-70 Mustang Muscle Car EFI Fuel Pump module was designed as a direct replacement for your factory pick-up and sending unit. There is no need to purchase a custom EFI fuel tank.

Over the years we have found out that valve tapping is misdiagnosed 90 % of the time the header gaskets shrink up and give you that typewriter sound so please read below and check closely. Also if a vehicle isn’t driven on a daily basis moisture collects in the valve lifters and the plungers in the lifters will stick because rust forms on the them. Best to change oil and filter and take the vehicle for a good ride and see if it gets better, if it does then start putting some miles on it weekly. Try to stay away from gas that has an Ethanol blend it is terrible for classic vehicles because it collects moisture.

Engine sounds like a valve tap but it could Be a Header Gasket leaking.
Here is what usually happens after about 500 miles the header gaskets shrinks up and starts to leak especially when the vehicle is cold. Easiest way to diagnose a Header gasket leak is to get a big bath towel start the engine up cold and hold the towel over the area that you hear the noise coming from if the noise changes then most likely it is the Header gasket leaking. You can try to retorque the header bolts to 30 ft. lbs. and if they keep loosening up use # 271 Loctite on the bolts. If the gasket has burnt through then new gaskets are probably necessary.

Occasionally we have a customer call saying on his Serpentine system it leaves no room to install an electric fan.   I have seen it before on certain applications sometimes if you have installed a 4 core radiator it is to wide leaving no room,  www.proformparts.com has slim fit electric fans. if that won’t work  Here is the easiest fix. forget about the electric fan and install a Flex Fan  it only needs less than 2 inches of clearance. note fans are available in standard or reverse rotation You must First determine which direction your water pump is turning either clockwise, or counter clockwise, Flex Fans can be ordered from  www.summitracing.com   To install the Flex fan remove the 4 Allen screws and the chrome nose cover from the front of the water pump, install the new Flex fan with correct length bolts with flat and lock washers this will give you the clearance you need. Check all clearances before starting engine.

The CSI ( Charging Circuit Integrated ) alternators that we use are 140 Amp, They are used around the world. they only require a 6 gauge wire from the Alternator to the Positive terminal on Your Battery, no other wires or plugs should be used. There are so many Aftermarket wire harnesses’ out there most of them are universal Harnesses, they should not be hooked up to a ( one wire Alternator ) These CSI Alternator systems are Isolated and work on their own.

Just run a 6 gauge wire from the terminal with the nut on the alternator to the positive Battery terminal the engine will start and charge the Battery at 14.2 volts. you will need to hook up a separate voltmeter under your dash to monitor your charging system.

You should also be sure when they installed your engine, that your engine must have a 4 gauge heavy duty ground wire from the engine block to the vehicles frame.
