My buddy swapped his 1980 k10. He has a 4.8 with stupid huge 228r cam and milled heads. Stock everything else. Even manifolds. Some local shop sold him a "performance converter" which was about the same size as a stock one. They said it was a 2500 stall. But here is the kicker. Its on a 8" lift with 40" Michelin military tires that have 1" thick sidewalls. They are literally 80-100lbs a piece. 3:73 rear gears. Also a stock rebuilt th350. I'm guessing about 150-175 to the ground. Maybe. He is delusional and thinks he can make 400hp to the rollers.

400hp with 40's through stock manifolds on a N/A 4.8? Maybe if he spins it up to 9000 RPM

he is in for a huge surprise. let him think he is gonna make that but in reality it might make around 200-250 rwhp if he is super lucky. lol
my tires are 84lbs each and those military tires are ALOT heavier then mine.
I forget what my 40" Iroks were but they were not light either but still not even close to the military tires

157rwhp is my guess Bob. Between those tires and that monster cam in a damn rev happy 4.8 I hope he is spinning it to the moon.

HAHAHA 144hp/ 138tg he is so pissed. Not sure where it peaked but he said the rpm limit is around 6400 now. Lol

No, a 4.8 with cam and springs will not go boom at 7200.
