Is that a 66 block? You are aware that 66 blocks came with inferior maincaps. Not all blocks that year had the weak caps but a large percentage did. If the caps are original its highly recommended they be replaced.
Thank You hangout for your concern... and yes it has already been done. I also consult my best friend, Larry Shepard... or his book rather :) His Hemi Book is a good investment when you don´t know experienced Hemi guys to consult. But again, FABO is great thanks to you guys...
