I thought I had really researched the hell out of my build. When I compared the specs of the AT and MT cams at the time it didn't seem to be that big of a difference. Obviously I was wrong. In any event, it's enough power for now. I'm working on the suspension, wheels and brakes this year. Next year will be the year of the "JWT 500 cams with meth" then I'll retune it. My goal is 500hp and with that set up I think I'll be there. A car junkies job is never done!
