Default Change from 8" to 10" converter

New pump gas combo it making more power than the old race gas combo. Trying to set up new combo to run a 10.00 class. Went out Saturday with the small 850, tailpipes and 260lbs of ballast in the car. Ran 9.87/135 with a 1.33 60'. It was 90+ degrees with a da of 2000.
Running an 8" ATI MRT converter that stalls at 5000. I have an ATI 10" laying around from the street car that stalled at 3500 with 500hp engine.
What do you think the 10" converter will do vs the 8". I know I will loose some 60'.
Thinking it might stall higher with more hp and be a little tighter down track. By the way I am launching with a trans break at 3800 now. Shifting at 6200 and going thru the traps at 6700.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
