Now we are talking! Ok, Jim, so what is the "optimum" compression ratio for the standard L-71/L-72/L-78/LS-6 cam (.520/.520)?

Now, I understand why Pete did what he did with his ZL-1: he needed the lash for the brakes and to make up for the ZL-1's natural lack of a bottom end, both due to the big cam. BUT, I noticed in his L-72 dyno test that he ran a lot of lash as well, not as much as the ZL-1, but still well off of the factory's 24/28 mark.

Pete: did you get the email with the muffler/crossover tests?
