Your rear end ratio is WAY off!! Your putting an engine that's built for mainly mid range in front of a gear that's use is low end. I would use at LEAST a 3:25 in that thing. If it's all city use I would go a 3:54. Do the math, measure your tire diameter and see what your cruise RPM will be with that gear. That car will want to run 120MPH PLUS with that cam & that gear. But it will be slow getting there. You will realize MUCH more performance by matching the GEAR ratio to your use than ANY cam change. But hey,,,,, that's just ME! Bruce Hevner
