We are a family-owned and operated business specializing in building custom high-performance domestic 8-cylinder engines.  We've been in business for over 40 years, having started by installing high-performance bolt-on parts for our friends.
Eventually this led to our desire to build up the engines so we acquired the necessary equipment and continued to grow our business.  At that time it was customary to rebuild engines and cylinder heads using factory castings.  Today, many of the engines and heads we do are built using the new castings on the market. 
Having come of age in the muscle-car era, that is our preferred market.

Our Operations
To maintain our high standard of quality, all engine machine work and assembly of engine components is done by our own shop personnel, most of which is done by the owner himself.   It is not sent out of our facility, thereby we maintain quality control.   

Some of the services we offer are: 

  • boring and honing engine blocks
  • porting and polishing cylinder heads
  • align bore mains
  • correcting lifter bores on Small Block and Big Block Chevy's from the muscle-car era
  • crankshaft grinding
  • reciprocating assembly balancing
  • decking and surfacing blocks
  • re-surfacing cylinder heads and manifolds
  • pressure checking
  • magnafluxing
  • stitching cracked cast iron blocks and cylinder heads 
  • dyno testing engines we build


Quality Matters
Our customers have come to expect quality work and that's what they get when they come here, even though it takes extra time to perform.
