Hello, I have an 86 mustang and I'm currently installing a Trickflow Stage 1 Cam in a rebuilt shortblock. My question is, trickflow's specs are calling for a minimum 9:1 compression ratio, but calculating my setup with the cylinder heads and piston head volume, I will have a compression of 8.4:1. Is it that important that I meet the minimum 9:1 compression ratio, I have seen other high performance camshafts not call for a specific range of compression ratios. Any ideas or suggestions would be greatly appreciated.
