Mike....this is what I got from my 8.7:1 compression 507" Cadillac. It did have some go fast stuff in it but it was all done by 5,000 rpm. 466 hp @ 5,000 ...535 torque @ 4300. I did a good home port job and installed larger SS valves. The red line is the torque curve...which is basically flat across the rpm range. It was well over 450 torque @ 3,000. Enjoy your engine!
