He is going to post his IDC's later. I'm glad this worked out. I thought a 2.9 for a GM hub was going to be impossible. It even looks good. Later bro

Thanks!
Thanks!
2.9" = 16psi
2.8" = 17psi
1psi is good for about 10hp.....almost.

I haven't hit the dyno since GM stage 2 and an Injen CAI.
I put down 242whp and 212wtq with just that done.
I won't be going to the dyno untill May or so....
I'm guessing i'm at about 265-270whp now.
