I was wondering how much HP a 6.0L can handle, the 01'+. Also, what would a 6.0L push with mods like, intake, headers, exhaust, cam, 125 shot?

 

i can answer this one, ALOT! with proper tuning i hit my stock 6.0 with 8psi of boost and a 75shot many times. the ET i ran with that set up calculates out to be ~580rwhp. then i decided to blow the thing up so i could get a better motor and i uped the boost to 9psi, ran it that way for awhile, then uped the the nitrous to a 100shot(on top of the 9psi), the first time i hit it with that the tranny let go. this was a built tranny from flp, they have a great reputation.

i am going to say over 500rwhp all day long and over 600rwhp fow awhile.
