My goal is to help you build your car with what is needed for your car. Don't spend extra money on gimmicks, but check out the services I offer. I put special attention to detailed and quality products.
I can help with a 'bolt in lump port kit' or a 'performance intake lump port head' work for your inline Chevy 194, 230, 250, 292 and 153,181, 2.5, or 3.0 mercury engines. Plenty of Chevy inline 4 and 6 performance parts in stock and ready to go.
Our services also include 12 bolt rear-end restoration and rebuilding. We have a wide selection of rears in stock and ready to build!
Check out this instructional video on how to add a bolt in lump kit to your head.
Recently, dyno testing was done on a Chevy 292 to test street speed parts. The same type testing was also done on a 250.
