not sure on the gearing of that trans to mate with that stall
but the 4L60E trans gearing, with 4.10s out back on 28" tall MT drag radials, with off the shelf yank ss4000 has put me to a 1.28 60ft at 3000 raceweight...+350ft da 520rwhp 440rwtq...
Also i tried the 1" spohn rear sway bar and it was junk, pony up and get a rear drag bar ~$400 night and day difference...

as a matter of a fact I have been working on it!!!!
im no big money pimp like you though! lol
im cerealous though, i've been seeing some cars make a big difference with a good gear here lately. as a matter of a fact I saw a stock bottom end car go 10.4s 3 weeks ago and go 9.9xs last weekend w/ just a gear change. but it is an ls3 bottom end

The 1" spohn sway is maybe good for a SI car but once you start making more power the body want to twist and flex in the rear unloading the one tire, with the preload from the drag bar and it being a ton stronger the car leaves like an arrow, both tires firmly planted in the rear with both front even in the air...
yeah I though the 4l60e was like a 3.05 ish...so a slightly higher stall might help you to overcome that smaller gear...
Spohn drag bar bolt in...there are alot of options now, I believe the UMI has better provision for shock clearance...mine rubs some on either launches or turns...

Not sure I could make it through the 1/4 with 4.56's on 28's with this loose of a converter. I did pick up some rear double adjustable Afcos though.
