CobraED Ed if money is no limit, cammer in a 600" cubic inch size. Rumor has it there is a couple of them being built. Jon Kaase has built some 600"+ boss motors and has new heads for this block. If I was looking at weight, cammer wins withstock setup. aftermarket block and heads with about a 550 pound weight range, again cammer. Cheaper to build and maintain Boss.
Big question is what looks better to the eye when the hood is raised, Got to go with a 58MM weber cammer just like Al's. Its perfect together. Now driving it with control is a whole new issue. Which ever motor in a cobra you end up with, hope you have a badge and alot of PBA cards to spare. Rick L.
