Knowledge &
Building a high-horsepower car is more than bolting on a collection of parts. You need a shop that understands which parts are right for your project, how the parts will perform, how they will work together and the modifications that will be needed. Mopar, Ford or GM, we’ve worked on them all.
Longevity &
A properly built engine shouldn’t blow up. Our 35+ years experience in the automotive performance industry allows us to know where & when we can make gains and the boundaries we must stay within. We are proud to say we have many race engines that have been “beat on” for many years without breaking.

Head porting is a must for many applications whether it’s a street car or a strip car. Simply hogging out material and making the hole bigger isn’t considered a “port job”. Knowing where to remove material, where to leave material and how to shape the material take many years of experience. Every head we port gets extensively checked and rechecked on our flow bench before, during and after porting to ensure it’s done properly.
