I have a 2003 ecsb 4x4 with a 5.3, I was going to spray it but got an awesome deal on a modified/improved Powerdyne. I know, I know I've read alot about how crAppy they are. This one has upgraded bearings, vented case, Kevlar belt. I only paid a 1000 for the entire kit. Question I have is on 9# with meth, what kind of power will it make? I have LS6 cam, exhaust, tune. Like I said i know they are not the greatest so don't try to flame too hard. Any input would be appreciated.

 

Anyone?
