Hello Joe,
I was wondering what kind of power plant (motor) that you were using. Was it a nailhead? Glad to hear you got out to the track. I took mine out for a ride today and I know who you feel.
I don't think a nailhead will push that mass of weight into the low 12's. 3950 lbs.
It's a 455, 30 over goobs of home head porting, TA C113, roller rockers, MSD Pro Billet Dist, New Demon 850, upgraded oiling. T400 trans, 3500 stall, and I think it's slipping so i'm saving for a new one. So I might see 11's with this upgrade alone!!
The rear is a 8.2 in 10 bolt with 355's and a TA girdle cover, rear air bags with boxed lower control bars.
