I'm looking for recommendations for a solid, reasonable engine builder for a set of 502/500 hp's or 540's. A builder in MA by the name of Mancini has been proposed by the guy who will install them. Anyone have experience with his work?

Just in cast you question was a typo for the state, MI not Ma, I do know of a shop in Michigan by Mancini. Ron Mancini was a big time MoPar Drag racer that was killed on the drag strip years ago, but I think his shop still exists in Clinton Twp.

Also, there was a Ray Mancini(Mancini Motorsports) (he was pretty much a bike guy, but was partners with a guy that did some pretty trick automoyive stuff) in CT. a while back, good guy, maybe he moved to MA????

Flow Technologies in Plymouth MI. They have alot a marine engine experience, and specialize in flow bench work. Full dyno facilities. He also has a couple of guys who were "stolen" from some other BIG marine engine companies also based in Michigan.

Reasonable prices, too. 734 454-4190
