Apparently I suck at drag racing...

So I'm about to make some changes to my car before I go back to the track. Some of the parts I just happened upon, so I picked them up.

First off is a pair of 26x8.5 MT ET Drags.
Second is a pair of Super Stock springs.

In addition to those changes, I think I'm gonna add a adjustable pinion snubber, driveshaft hoop and a Linelock to make burnouts easier.

Any suggestions on a starting point for tire pressure and launching rpm?
18 psi cold, launch rpm is test test test depending on converter, put a driveshaft loop before running sticky tires. I run my adjustable snubber 1/4" gap with driver in the seat.
