What kind of power gains are possible?

5.7 > 4.8

Yes I know lol

All bs aside a stock 5.3 makes about 220hp to the wheels, if you manage to get 310-330hp from a cam swap call it a good day.

Yes, a stock 5.3 will make 220. Add a tune, and bolt ons and you can get 250+. Add a cam and over 300hp is pretty reasonable to expect.

Thanks for the info, Im getting the cam and Heads for 1200 installed, I chose that stall with a lil help from Nelson and the shop im getting the stuff from. I plan on driving the truck 500 miles across tx to work 2 times a month. I think if I can get 370 at the Wheels that would be respectable power from the truck and motor combo. Id be happy with that. It will prob leave most trucks at the red light when you want to get in it, so I can live with that.

37x rwhp i was running 13.0s so yea youll handle most trucks pretty good.

5.3, LT's, full exhaust, tr220, 2800 stall, built trans, 4.10's got me 330rwhp and 13.6 1/4 mile.
My new iron 5.7 with 11:1 cr with a TSP228 milled 241's and all other mods the same got me down to 13.1. So I'm guessing I'm right around 370-380.
Your planned mods should make it a fun truck.
