Finally got around to getting it retuned after the 4R70 swap. before it made in the 650s with a t56 on 7lb gate springs (netted 8-9psi) on 91 oct. I swapped in a built 4r70, ptc converter and changed gate springs to 10lb springs (netted 11psi i believe). We came out with, i shit you not, 666rwhp with a little converter slip.

Obviously that seemed like a short pull. lol 4.10 gears on a turbo car with a auto will do that. Built rear is to come hopefully sooner than later as i can't really race it like it is since I'll top out 3rd gear well before the end of the 1/4. Seriously...105mph top speed in 3rd...i was speechless. I know the converter slip had a little bit to do with it but i was expecting it to top around 125ish. Also tire size, these tires are 315/30...also not helping.
So yay more money to spend...tighted up the converter, build rear end...turn up booooooost. lol even with my hoosiers on, in 3rd gear I'm roasting the tires from about any speed.
