5.3 With Z06 cam
This is the first start of the 5.3 going into a 78 trans am. extreme!!
Trans AM FM MPT70 5.3L LM7 528hp 491tq (1BAD LS1)
This is my current setup, Front mount Master Power T70/.96AR turbo, Pullout 5.3L LM7 8.5:1 compression, 317
heads, 02 ZO6 Cam, COMP 7.425 pushrods, I Custom Fabbed the Merge pipe and
down pipe, FMIC, 9" 370 gears, VIG 3600, Tuned by me (1BAD_LS1 TUNING
It made 528HP and 491TQ with 22* timing, 14psi, 11.5afr at only 5600RPM
(trans was slipping like a mofo) it will make 600hp + easy! Those are the
best numbers the car put down because the trans/converter kept getting
worse and worse....
Those numbers were also made with a high stall auto Vig 3600 with a cracked
hub, a stock slipping 460e, and a 9" with 3.70's !!!!!!!!! I need a better
tranny/stall/gears because what i am running in not turbo friendly at all!
UPDATE... installed a th400 trans, new rear gears, and a few more psi!!!!
no Dyno numbers but i
would bet the car would put down close to 700HP!
