Take your rpm at the stripe and compare it to what the number is when you take mph, rear gear and tire height.

We put the motor on the dyno when the heads flowed 400 cfm and it made 872 hp and I think it was 770 ft lbs of tq.

145.31 x 4.30x 336/29.5 = actual rpm(7116)
I didn't know what tire your running i guessed at 29.5 and if right your slipping almost 900 rpms on top, if taller its worse even.

Going by Darby's numbers, that's 11% slippage.
