i didt want to take the 342 out but i have a few weeks before i can get dyno time. everyone was right about the 292xfi cam it pulls hard 3500 to about 7.
whats the shift points on a 3.90 vs a 4.10 will it stay in 3rd in the 1320.

I have to shift to 4th but I don't have a cam. You may just have to shift gears quicker than i do

With that cam I would do 4.10's, at least.

if your on a 10bolt, i would do 3.90 unless you are planning on replacing your rear sooner in the future. I always hear about 4.10's breaking the rear.

Go 4.10s. You won't break anything unless you hook hard at the track.

Not always true Joe. I've broken 4.10s on the street. The 7.5 is doomed when you start making power regardless imo

just what im used to stock i was shifting 6000rpm 1st and second and trapped 6300 holding it in 3rd. im afraid of breaking the 10 bolt so i would roll it out slow out of the hole i was averageing 13.5-13.6 at 102 103 with 2.1 sixtys with longtubes and exhaust only. i guess whatever i find cheaper, i need some drive time this summer next year comes the 9 inch
