Exhaust and tune will get you there. add a came too and you'll be there at the rear wheels.
What makes the 5.3 High Output crate engine so special is that the GM engineers have added a GM Performance Parts custom cam and Grafal-coated pistons. With these simple upgrades, the 5.3 HO kicks out 332 horsepower and 352 lb.-ft. of torque. And, just like the stock 5.3, the 5.3 HO is capable of thousands of miles of dependable service while returning outstanding fuel mileage, thanks to the superior design of the LS Family of engines.

i ran across a 5.3 H.O. and i seen the hp out put and i was in shock.
i had no clue of a 5.3 STOCK from G.M. making those numbers.
i have been looking at a 5.3 or 6.0 to swap into my truck.
the 5.3 gets good MPG. i will assume the H.O. does to???
i can buy 5.3s ALOT cheaper than i can a 6.0
