Finally have a real rearend and tires... Looking for some launch tips as this will be the first time I'm going to the strip with real tires and a bulletproof rear-axle.
H/C/I 404, m6 w/ textralia, 3.73 S60, 275 M&H DR's.
Have never cut a 60 foot faster than 2.1 i think.
What RPMs should I try launching at and should I feather it or do a straight hammer drop? Any tips on rear PSI? was going to start ~20.

I messed around with radials and a 6 speed and just got frustrated, do yourself a favor and get a bias ply.
For a radial at Lapeer, I cut 1.8's on a Nitto 555r 275/17 at 18 psi with a fast let off of the clutch from around 3k rpm.
For a street Bias ply I would recommend Hoosier QTP
For Track a 28" stiff wall, I run a M/T ET Drag 28x11.5x15 and cut high 1.3's at Lapeer.

nice rear end , I am jealous
you will still need a bias ply/stiff wall slick to get best traction but somewhere in the 13-16 psi range hot (check after your passes) and you should do much better than in the past even on your dr's , but the other limiting factor for you now will be suspension to be able to really let it eat , drag bar , drag shocks , torque arm etc...I don't see anything listed in your sig - do you have any aftermarket suspension in place ?

This is exactly what you need to do. Wouldn't hurt at all to have more gear in the car either. My buddy races a N/A LS1 T56 that runs 10.30s all motor. he is running 4.57 gear and his car only weighs around 2500lbs. Some 4.30s would be a night and day difference to get that heavy car moving.
