I don't care what the dyno says. The auto will beat it at the track every time.

well, the 427 made about 960rw on 12 lbs on the 6 speed, the bigger turbos didn't help much at low PR's. But as boost went up it can be seen

347 at 18 psi made 950rw on the T56 for example, but the 427 at 16 psi made 1090 with the T56... at 20 psi through the TH400 now it makes 1030 rw. need to push it a little higher but about out of injector.

Honestly... With a good converter on a fresh 4L80E what % of parastic loss? 20%? That may be a little low. I'd think it beat a T56 everytime at the track

Never felt the need to push it on pump gas, I made 680 rwhp at 11-12 psi on 91 octane with my 347/T56/T76GTS/12 bolt. On a mix of 109 and 91 it made 810 rwhp/rwtq at 16 psi.

Nice!!!
I think its safe to say the car was close 1200rwhp with 20psi if you have T56?

should be in the ball park if my math is correct.
I will probably go back to a T56 after I do some more 1/4 mile stuff just to get that out of my system.
