RE: horsepower

I have the same size engine but in a newer model and the engine puts out 295. Not sure what the power to the wheels are.

RE: horsepower

Around 230-240 to the wheels. Prob 280-285 at the crank.

The hp on the 5.3 should go something like this. I'm not 100% on it.
99-00 = 275hp
01-02 = 285hp
03-05 = 295hp

RE: horsepower

Maybe I got the years messed up. I was kinda disappointed when I got my truck and found out 99 was the weakest year for the 5.3, but after tuning it I'm over it.
