Home of the HI-FLOW lump kit.
Our 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. We put special attention to detailed and quality products.
We can help make 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.
There is also a instructional video on how to add a bolt in lump kit to your head.
Our services also include 12 bolt rearend restoration and rebuilding. We have a wide selection of rears in stock and ready to build!
Recently, dyno testing was done on a Chevy 292 to test street speed parts. The same type testing was also done on a 250.
Thanks for visiting our site! Hopefully you will find the information you are looking for. -Tom Lowe
