PRECISION BUILT ENGINES

   

Large or small, Chevy, Ford, Mopar, Pontiac, or Ferrari...and the list goes on.  We are not brand specific, we build them all, from a stock rebuild to a full-blown race piece.  We can update your current engine, freshen one from another engine builder or start from scratch.  We will work within your budget to give you the most for your performance dollar.

Each engine is assembled with the best combination of parts available to fit your specific application.  All clearances are checked and documented, including  all part numbers and additional notes on an engine build sheet provided with each engine.  Every engine is then run and dyno tested on our in-house DTS dyno before it leaves the shop.  To view a sample build sheet CLICK HERE.

Listed below is just a small sampling of the engines we have built.  As confidentiality is a key concern in our business, information and images of most race engines we have built or tested cannot be shared.

This is a 292 Ford for a restoration project that was being done on a '56 Thunderbird.  In addition to the engine, the complete drive train was redone in our shop while the car was in the body shop.

Here are a couple of the more exotic projects we have been involved with.  At left is a inline six from a 1952 Marauder, a British roadster that is the only known example that made it to the US.  On the right a V-12 Ferrari awaits its turn on the dyno, next to a 600+ cubic inch BBC.
