So 106 will be good? if we went to 104 could be too much closing the valve earlier yet?.. What I meant is if i go to 102 from the other comment, doesn't the idle get choppier being a earlier ICL or no?.. I plan on doing the dist mod also.. thinking this cam will like about 15-18 initial? Being a street car it shouldn't be a dog even with the his current gear, and the 11" 2400 conv right?He wants to be able to have a nice power band and not be a pig til it comes up on the cam when he tries to goose it.. thanks guys! Really appreciate it!

With the availabe replacement pistons, I think your compression will be closer to 9-91/2:1 allthough I have Aluminum heads, I used a thinner head gasket to get compression at 10:1 the block was also deck quite a bit. I have often used the 87 octane to top off the tank after racing and street drive my junk with no ping. The only time I got pinging was before limiting advance. Good luck, see you this weekend??
