why don't crowbars float?
i would go a 4agze, 20v, or a 3sgte. but these have efi
why don't you put efi on? as by the time you put these kind of donks in, you will have to fork out for a decent set of twin sidedrafts (or something) and a manifold to make it go any good, and end up paying more than efi, which is easier to maintain
