What are your goals for quarter mile MPH? That should ultimately make your decision on rear gear ratio. I went with 3.42 posi and it would have been helpful to go 3.08, unfortunately I wont be able to do that when I go to a spool.

3.73s and a 26 tall tire have put a few guys out of their usable RPM range around here, and 4.10 would be a nightmare for them. On the other hand, when I had 3.73s on my old setup a few years ago, it worked out pretty well because I wasnt as fast.

Im shootin for the mid to low 10's. In my 10bolt i have 4.11 and they suck balls. I was at least going to go to a 3.73 gear, probably going to end up with 3.42. NA with no tune its at 370rwhp and i want to hit it with a 150 shot. BadAzz could you pm me some info on the dana60 and when the group buy is gona happen??

With that th400, a 26" tall tire and 3.73's you'll probably be topping your car out at around 136-141mph, depending on how high your going to be reving your motor. I think that you should be just over 150 mph, with 3.42's... Those are most likely the gears that i'm going to go with too.

150mph is right where i want to be, so it sounds like im going with the 3.42gears. Now its just down to a rearend ?? I would like to find out a little more about the dana60 group buy, otherwise getting the 9".

That gp on ls1tech looks good , but i was lookin at both moser 12bolt and 9" from Spohn.The 9" is about the same and the 12bolt is cheaper, I would like to here more about the local gp on the dana60.

Went TruTrac because I didn't want a locker. Sees too much street time for that.

Sea level would require a larger tire to get the best trap out of it. Motor spins to 6700.

EPP shipped it to my door for $2400.

Sorry for the delay, we were waiting for the dealer info from Strange to arrive. I was going to link to the thread, but Scary Guy already covered it for me

This shit sucks,I just ordered a bunch of stuff from Spohn yesterday including a 9". I dont think they shipped anything yet, so I going to call tomarrow and see if I can cancel the rearend. I really like the s60 alot and for that price you cant beat it. Less horsepower to drive , bigger gears im in..maybe . SO if can get out of the 9" I'll sign up for s60. I thought that the s60 gp was going to be a myth , and was running out of things to do ,so i screwed myself. we'll see.
