Thats sound pretty badassss for a 4.3 vortec man. I really am not familiar with turbo or superchargers and all but i'm sure there will be allot you have to do too and change out i'm assuming. I want to twin turbo my 5.3 also just don't know which turbo to use and how much would it cost? I hope someone can chime in for allot more needed info bud!

sounds about right. i was gonna supercharge it but my buddy talked me out of it. one group of ppl got over a 1000hp outta a tt 4.3 vortec.

Pushing that much power I hope you are going to stiffen the frame. I don't know for sure but that sounds like a frame twister to me. What kind of traction adder are you going to use? 1000hp in a Jimmy sounds nice. You have to post some pics along the way.

oh definitely. im not gonna be pushing that much though. i honestly am thinking it all up day by day as i get ideas. my buddy has a set plan for it but im very creative and always thinkin of somethin to do with it which is a pain at times. right now my main project is finding the front hinges for my dang moonroof. so darn annoying.

Do head work to lower the compression, cams will help, go with a lower duration exhaust. Be sure to add an extremely large inter cooler for twins. Water to air would be best. Even meth injection. How big of injectors are you going to be running? New fuel pump? Or just a boost-a-pump? remote mount system? Or manifolds?
