Cam recommendation
I agree with Coyote. Why is your valve lift so low? Are your springs maxed out at .500? I've got a Comp Cam in my blown 408 and I have a 110 intake C/L and 114 separation. You don't want overlap when trying to build boost. Also, is this on a Magnum or LA block? Because the year range in that cam card is for two completely different oiling styles for cams.
