I run one (4972) on my 340 (stroked to 426) it's a pump gas engine that makes 450HP and 495 TQ running a stock intake and stock exhaust manifolds. I swapped on an AVS and an 850 Holley while it was on the dyno, the TQ gave the best overall numbers.
*As others have mentioned, I can build you a TQ if you need one
