What are most guys running in there satge II cars for a rear end and gears thanks .
 
I have one with a 9in ford and one with a stock 8 1/2 ,If you are building a rear from scratch i would go with a 9in.
 
Here is what is going in mine. I had a plain old 9" in there with Strange 31 spline axles and I broke one. So I'm stepping it up a bit and putting 40 spline stuff in there.

I have the 33 spline in mine! Scott what boost were you running on that et. Iam also running a 28" tire with 200r4 tranny.
 
Alan what cam was in your motor?

It's a stage 2 head so the power band is going to be higher then a conventional head. My cam is just over .609 lift with a 242 dur @ .050. Its a solid roller cam with comp's extream street profile lobes.

Cam

Thats way diffrent than mine.Iam running a roller 212/206 cam! lift on intake is 482 and on exhaust is 467 thats what the cam card said i hope thats right that iam reading.
 
Moser 12 bolt w/33 spline axles. 4.10 gears. I may try 3.73s in the future. Depends on how well I get my launch worked out. With the 4.10s, I'm crossing the finish line at 7550 rpm in the 1/4. A little higher than I'd like.
