Well I deiced to rebuild my bottom end to raise C/R and went with a bigger cam. Before the rebuild I had a stock bottom end, Alum head and intake, 1.65 roller rockers, 264/264 110 cam(advanced to 106), Holley 390cfm 4bbl, DUI and headers with x pipe and 2" exhaust. I had another block zero decked and installed flat top pistons. I also switched to a 274/274 110 cam, Advanced to 108 after talking with Clay Smith Tech. C/R went from 8.5 to 10.6. Car runs better to sure how much yet. Going to dyno in a few weeks after I put some miles on the car and install MSD Atomic EFI. What is odd to me is the car is not as loud now. It is a lower tone and smoother sounding. Also Mustang Monthly is following again.
