284/484 MP cam install
I've ran that cam in a build very close to yours and really liked it. I installed it straight up. You cam move it around and see where the best power is. The comp cam extreme engergy has 4 degrees already built into the cam when it was ground. You might want to try installing it with 2-4 degree advance but without back to back track times I'm not sure you will notice that much difference. Just my two cents.
