Do I need a High Price Ignition System to be fast?

No.  We use all new race prepped MSD HEI Systems on all our Chevy's.  We have built engines that turn 9.90's at 8000 RPM without a problem, we also use small body electronic distributors for vehicles that need clearance at the firewall --- along with TACH cable drive for early VETTES


Which is better Carb or Fuel Injection?

If your vehicle is equipped with factory fuel injection stay with it.  We offer several upgrades to make it perform better. We are currently offering the MSD Electronic fuel injection system it is a great system if you want to go from carb to EFI but it will add several thousands of dollars over a carb system. 


NASCAR and NHRA still run CARBS.  Our experience and a number of independent racers will tell you that there is no real gain in power.  The injection system is usually better on emissions and that’s why big government secretly pushes it New CARBS are very reliable they are designed and machined by CC machines, the secret to any fuel system is to be sure you have a perfectly clean tank and lines --- note all fuel tank rust out internally after 20 years.  


Should I use a carb with mechanical or vacuum secondary’s?

We recommend vacuum secondary’s  for engines that are used on the street. 


    Which Engine Combination is right for my Vehicle?  

This is one of the most common questions our technicians answer. We will ask you a list of questions that will help point you in the right direction.

For example:

A.       What is your car or truck being used for?

B.       How often do you drive your vehicle?

C.       Is idle quality important to you?

D.       Do you have a budget your working with or don’t want to exceed?


These are just a few of the questions we will address to make your buying decision the proper one for you.  

Let’s say for example you have an early Camaro with a 5.0 liter that has high mileage and is tired.  You are looking for something you can use as a daily driver with good low end torque plus midrange horsepower for highway use and your budget for a complete turnkey engine is under $6,000.00.

Engine Factory offers several variations of the 350 --- they are available in different colors, finishes, wire colors etc.


350 / 300 HP Stage 1 – One step up from stock engine

350 / 350 HP Stage 2 – Two steps up from Stock engine

350 / 400 HP Stage 3 – Three steps up from Stock engine

350 / 450 HP Stroker Stage 4 – Four steps up from Stock engine


We would recommend the 350/350 HP version as being a good overall fit for this customer.  It is worth mentioning though that all of our engines are very streetable.  Just that some are more aggressive than others.

Will my factory Transmission withstand the added horsepower?  

This is a concern for people wanting more power but are worried that their factory tranny is not up to the job.  That is why we usually say that your factory transmission should bolt up and work great as long as it is in good shape. Of course we do offer new transmissions talk to your sales person,  As you get more and more radical with an engine the transmission can receive some upgrades for instance using a higher stall speed converter and / or put a shift kit in for stronger shifts. You have control over the gas pedal so you have ultimate control.

Can I swap to a different or larger engine than what I currently have?  

This is a yes or no answer.  Whenever your swapping out to a different or larger engine some questions that would need to be addressed.  All small block Chevy’s will interchange.

1.      Will all your existing parts ex: Pulley, Brackets, Transmission, exhaust etc. switch over to the larger engine --- Yes all small block Chevy’s that we build have the same bolt patterns.

2.      Are you committed to spending the extra labor time and expense to making the transition work if it is not a direct bolt in swap --- example going from a Small block to a Big Block Chevy.

3.      Will you see a significant gain in horsepower in making the change --- Yes more cubic inches result in bigger Horsepower!!!

The good news is that there are some engines that can interchange very easily.  One very popular upgrade our customers do is to upgrade from a 305 to a 350. This is pretty much a direct bolt in with the proper setup.  Speak to our Sales Tech staff regarding swaps and they can give you some input.


Engine Factory knows the pride our customers take in restoring their cars.  That’s why our engine builders pay special attention to detailing the overall appearance of your motor.



To insure quality and performance, each engine is test run for approximately 45 minutes  During this time the cam is broken in, all valves are adjusted, the carburetor is adjusted and the ignition is timed.  All systems are checked to be sure that there are no water, fuel or oil leaks under running conditions.  When you receive your engine, it is ready to drop in place and can be installed with total confidence.
