My 383 has a good bottom end, Eagle rotating assembly and JE forged pistons. With a nice little roller cam and 195 or 210 AFR heads I should see over 500 hp. With the CNC Victor Jr heads the 572 should see 700+hp and big torque. With a stock convertor and little traction the stock GMPP 572/620 did 12.2 @ 115 mph in my old 454 SS pickup. It's well over 4600# with my fat butt in it! I just re-did the old SS to make it a bit more streetable. Now 468 and 700r-4, out of the box it did a 12.9 @ 107 mph. That was just putting it in "D" and pressing the loud peddle. It also needs a better convertor with the cam and weight of the SS.

Not sure yet but thinking!
