Throwing this out to anyone who has experience with Marine SB Chevy builders. Old engine is DUN, so I'm looking for recommendations for engine builders that build a good Big ci small blocks that would run well in a jet. Nothing smaller than 383, perfer something a little larger based on a 2 part main block. Could go to a single if the case was compelling. Avoiding LS due to a lot of money already spent on an Eddie Marine exhaust system with SS risers. Any One? Not looking for someones car engine, want a well built engine that will last and has some testimonials to other work they have done.
