Re: comp xr270hr roller cam

Looks like an ok combination
I would be leary of the 600cfm, I think it is to small, at least 650 cfm
the only thing I worry about is your 2.02 valves will not help you until you get over 4200 rpm so your best power band is not utilized real well.
Maybe look at a higher lift cam, and a 650 cfm carb
