Any help appericiated, what kind of gains will I achieve with hp/tq or stock
Ok hears the deal, I have an 07 gmc Sierra classic with a 5.3 with stock 862 heads. My question is what kind of power gains will I get from the following. If this matters it's a crew cab short bed.
210/218 .551 .551 112 cam
Pacesetter longtube header
Ls6 valve spring
3200 circle-d converter
3.73 stock gears and
I'm thinking about swapping out my stock 862 heads for 243 with little head work to them.

I'm not good at guessing hp/tq numbers, but I can tell you that it will be a nice combo for sure. I'd up the gears a tad bit more to 4.10's though myself (what size tires are you running?). tdrumm used to run that cam in his 2wd rcsb, and it was excellent, even with stock heads, converter, and gears. Each time he modded it more, it responded even better. By the time he was done, the truck had WCCH StageI 5.3 heads, 4.10 gears, a FLT Level5 60E, and a Yank TT3000, and I felt that it was a perfect match. I remember Tom getting used to the converter real fast and wishing that he had went with a 3200
