I ran the 266/272 on a special centerline of 110. I then had the same cam on 108 C/L. To make a long story short, I was given a motor with the 262H cam on 112 centerline camshaft.All these grinds are from Crane Cams. The 262H has performed the best. I have same motor just forged pistons and a 2.50 or 2.73 read ratio. The larger cams did not run better because I needed to make other changes to the motor, which I did not and did not want to. I believe the real problem was the 2.5 rear ratio, poor heads( stock), converter in transmission (automatic). I would not go bigger on the cam unless you are ready to do other work and money. Bigger cams do not keep making the car go faster. Everything must work together to make it happen. I worked in the Crane Engineering dept. for many years, but still made the wrong camshaft selection on my car. Keith Cooper
