Update... been running the crap out of this thing... Decided the 4.30 gear wasnt making me or the car happy, so i installed some new Pro 4.56s and stud kid on the mains. Solid crush sleeve, as well. Taking it out for the 1st time tomorrow, with new gears. Main thing was , the 4.30 softened up the launch too much, and slowed me down on the tree. It did run 11.43/116.50 a couple weeks ago in decent air, though. I have my 350 trans back, and its ready to go in the car, but, gonna run the 400 trans a couple more weeks, with new gears, to make sure all is well before i go tearing into it again... its gonna be hot tomorrow, so doubt we will see good #'s of any kind...hehe
