New PB. Finally had a clean pass with the 2 step. Last time I went to the track with the 2 step, I ended up snapping the front pinion yoke in half on my 9 inch and ripping the rear of the driveshaft to pieces lol. Went back this past Friday after putting a billet pinion yoke on the 9 inch and switching to a 1350 u-joint on the driveshaft and ended up with the below picture, left lane.
10.6@ ~132 with a 1.57 sixty ft
Full weight 6 speed car running 7-8psi
I think she still has more left in her as she sits. Drove to and from the track getting ~30mpg's. Can't beat that with a stick, no pun intended. Feel's wonderful to get a full pass in the car and get in the 10's on such low boost.

Haha, thanks guys. To answer a few questions that were asked:
The T56 was semi rebuilt locally. Steel 3/4 fork, carbon synchros, billet slider keys is about the extent of the mods.
I am using an LPE LNC-002 2 step set to 4000 rpms and pulling about 4* of timing. This was only part throttle though, basically enough to sit on the 2 step.
Clutch is a McLeod RST. I smelled burnt clutch last time at the track pretty bad on one pass. This time I smelt it less after. I heard that with a twin disk this will sometimes happen the 1st couple of hard launches until it embeds.
And the 30MPG was verifed by filling up, driving on the highway a few hundred miles and then filling up again. I've also checked this via my Aeroforce scan gauge as well. Its a 9:1 383 with a small cam that's a reverse split and low overlap. I run a 3.50 gear and a 295/50/16 drag radial so cruising on the highway the car is only turning 1800rpms or so
I think based on my 60 ft and mph i should be able to knock a couple tenths out of it. My previous best 60 ft was only a 1.85 so this launch caught me a bit off guard lol.

Being in the 1.5X sixty foot is about as good as I expect with my weight and power. I do think I have another couple tenths at least based on my shifting....I was caught a bit off guard when the car launched as well as it did. I made 560 rwhp with 3700 rw, An that old launch method used to do the same to mine, try revving it quickly between 5800 and 6300 rpms, just stabbing the throttle very quickly. That way it leaves at 0 vacuum or a lb or 2 of boost and you pull the wheels a little and leave pretty hard.
