First time out Results

Didnt go as fast as I was hoping but had a lot of fun. Car wheel hopped like crazy during the burnout and could not get a decent launch no matter what. Felt like it launched ok, just needed higher stall converter. It currently just has SS springs with monroe shocks. I had MT Et Streets on it and aired them down to 18psi and launched from about 1500rpm. The car has an OEM converter which flashed at 23-2400rpm. Timeslip is below:
R/T .274
60ft 2.12
330' 5.839
660' 8.826
mph 82.50
1000 11.42
ET 13.61
MPH 102.62
The car went thru the lights at 4700rpm (3.55 gears w/ 26" tire)

I am thinking 3.91s, 32-3500rpm converter, and working on the suspension. Stiffer shocks, clamping the springs, and a pinion snubber will be things to look into to help improve ET.

How does the time slip look? Does it look like it is ET'ing where it should be? Should I even dig into the motor? I would like to get this down to high 12's.

Thanks
