I think turning a big 6-71 is just going to kill making better HP than you could w/a smaller blower,but a 6-71 looks impressive!
That cam is OK, & you will hear the loping,if you want a smoother idle,widen the lobe center to 114-117 range.
Multi 1 barrells??? how much CFM?
If all tuned & running good,400 HP to the wheels?
Just a guess.
