will 5.7 heads help me any on my 4.8 p1sc? and i was wondering if you all would post you dyno #,track times and random procharger vids.. thanks

Robert

 

My truck made 423 rwhp / 425 rwtq on a all stock internal 5.3L, with a P-1sc with stock pulley. Since then I changed exaust, added Meth, and got a lot better tune.

Sorry no times, I going to wait till I put my Head & Cam 6.0L till I run again.

 

Dunno if it will help, but check out the "head help" thread I posted in the internal engine mod page.

D1SC install on '04 silv, 4.25" pulley (10-11#'s), 3-core intercooler, all stock 5.3...425rwhp, 430rwtq

sorry no track times that I am aware of

 

thanks keep tem coming guys
