whats the highest rpm full bolt on l98

i might need to play with the goveners in my 700r4 next spring. Whats the highest rpm i can shift at with a full bolt on l98?

At the moment i have a hsr, cai, headers, 3" flowmaster, msd, afpr, pcm for less tune, 3:73, most free mods. Another question, would you guys suggest a set of 1.6rr to make a few extra hp? typically what should a car like this be shifting at. im thinking no more than 5300rpms.

ive been reading about bolt on l98s trying to hit high 12s makes me think after the following i should be low 13s with some nitto drags 12s might be possible.

im also in the process of selecting a good stall speed, if anyone knows what would work well let me know, im guessing around 3k converter.

Stall speed depends on the setup. You want maximum torque and still be able to hook if it's a drag strip application. For street cruising my stock 350 responded very well to my 2400 RPM 9.5" converter. Stall flash is depended on the motor output. A converter will obviously flash higher behind a BBC than a 305 due to extra torque.

My experience has been stock TPIs are out of there power range by or at 5000 RPM. Since you have a stealth ram yours might breathe better.

Either way I would throw it on the dyno and check it out.
