Default Re: Big Block L-72 Question.
According to the Chevy by the Numbers book, the '66 had more cam duration, different heads w/slightly larger combustion chamber in the head, and a different intake than the later L-72s. Kind of nit-picky stuff, and I honestly can't say if any of it makes any difference. [img]/ubbthreads/images/graemlins/dunno.gif[/img]
