my old 4.8 got put on the rollers today
#1
I dont have the truck any more but keep in touch with the new owner so I figered id share... 733hp 645tq. They were hitting up to 24psi on it however it was on 20 inch wheels and a unlocked 3800ish stall which I think they were pushing through pretty hard seeing how low the torque numbers are. Never the less it was kind of neat to see the 4.8 hit those numbers under the circumstances being it was all stock just a 212-212 cam and head studs.
