I'm currently running a 63/71/13 over a 91. Makes mid 900s. Drives well but, I run a higher stall converter and a gated floor shifter. Shifting manually I can drive pretty much smoke free, if left in drive, not so much.

I also have 62mm and 66mm wheels and covers that I swap in sometimes. Not much difference between the 62 and 63, 66 spools a little slower.

If you need max power for racing or pulling, it works well. If you're trying to build a hot street truck, I'd sell it and get something with a tighter hot side for quicker spool.
