We custom build engines for all show cars maintaining original specs and serial numbers. With the advanced technology we use today your engine will be far superior to the original.

We build muscle car engines from mild to wild. Before you buy a crate engine come and compare the quality of our engine to a crate engine. Instead of settling for a production line engine built to their specifications let us custom design an engine to fit your budget and individual needs. We also have several excellent stroker and performance packages to choose from.
