Hey Jeff, I raised the compression to 14.1 and advanced the cam 4 degrees. Steve did some additional grinding and freshening on the heads. I think that advancing the cam woke up the bottom end more than anything else we did and it didn't sacrifice any top end. Other than replacing all 4 tires this spring, the chassis is the same. The slicks are hooking much harder than before. I think the additional torque is making the suspension work better with the additional shock to the tires. When are you getting out?
