Nicks Garage, 572 HEMI, Here we go....
Just took a peak at the next largest Hemi Nick has ever tested.
528 made 610HP/660TQ which is 1.15 HP/CI and 1.25 TQ/CI.
572 made 734HP/724TQ (on my dyno) which is 1.28 HP/CI and 1.26 TQ/CI.
Applying the same factors as the 572 would have the 528 @ 675 HP and 665 TQ. Come to think of it I wish he could put up the graph of the two engines, I'd like to see the shapes. J.Rob
