Thanks
I had a talk with a great tech at Comp Cams, Justin. I described the project and he recommended going with large ovals such as the heads that came with a ZZ502. GM performance p/n 12363391,
valves 2.19/1.88, 110cc semi-open chambers with a intake such as a Victor 454-O/4500. The cam he suggested was a #01-424-8,
242/248 @50 Duration, 545/560 lift. What do you think?
