I am trying to find the right cam and heads to use with my Procharged 4.8 @8lbs. I am also trying to decide whether I should port and polish the stock heads, or go with a set of aftermarket ones. Any help is sincerely appreciated.


*2002 Black RCSB 4.8L, Procharger P1SC@8lbs. w/3-core, BBK 80mm TB, ASM Headers, 2.5" straight pipes w/2 40 series flows, Westers tune, e-fans, built 4L60E w/transgo, Yank tt converter, Eaton posi, 4.10 gears, $12K in appearance/stereo junk*

 

I personally would run the stock heads with a P&P job instead of shelling out the extra $ for new heads. on the cam I am not sure, but a call to a few serious ls1 shops like futral will cure that. How's the truck sound with no cats and the 40 series?

 

Thanks for the input. It sounds great without the cats and the 40 series. I used to have just a gibson cat-back and it is sure a step up from that. The Gibson set up sounded ok, but pretty hollow and sounded kinda crappy at high RPMs.

cool, I run dual 1 chamber flows on my regular cab and I have lost to much lowend and their to loud for everyday driving.
