This thing has lots of issues really. It's got it's tongue hanging out at 6k, and it's beyond done pulling. So more gear would mean more finish line rpm. Crosses the stripe at 5500 already, so there really isn't much room in the room range to fix that. However the converter is slipping 25%, so if I could fix that the rpm might come down. It's possible that the gear would help the slip too, but I don't know that for sure.

Also, I can build more boost on the starting line, that's not an issue. But the 255/60 drag radials won't take any more. So again another reason why more gear would seem to be going the wrong way.

Hard to say. I am 100% certain that the combo could be better, but I'm not sure if I want to spend any more money on the 8 3/4" (how hard can you really leave in a 3700lbs car and a Trans brake!), or if I want to put more cam in it for done more rpm (with the stock rods!)
