It's hard to quantify with only brand names. For instance, are you considering long or short tube headers, what lift/duration on the cam, for starters.

The cfm on the carb sounds conservative, and single plane manifolds are known for poor torque at low end, but the relatively small cfm carb could counter that if you use long tube headers, ultimately the cam runs the show- if you don't match everything as a unit, then you'll have a premium octane dog that can't run with the big boys.
