Official NBS 4.3v6 to GEN 3 V8 swap Guide

[rmagni]

I have a 2008 Silverado regular cab short bed 4x2 3.23 rear gear with v6 auto I want to swap to a v8 my 08 is apparently different from the earlier models no one can reprogram the ecm/tcm no cai nothing for it. Even though it runs smooth it lacks power what year ls motor should I look for I want to keep my cruise and a/c my truck came with an electric fan are there wiring provisions for it to be run by the stock ecm/tcm thanks for any/all help

Go to a junkyard and get a wiring harness and mounts front drive accesories, any of the motors will work as long as its a 58 tooth reluctor wheel

Or just put a nitrous kit on it and run it with a 50-100 shot until the engine craps the bed, then put the V8 in it. You're not going to get squat for it when you sell it most likely so you might as well have some fun with it while its in there.

I may be moving soon I live in Florida now and I may be going to Wichita Kansas. So I don't want to blow it up just yet, the motor has 4K on it I have a miser car I drive back and forth to work. I see you are from Denton I grew up in Lewisville "Home of the Fighting Farmers"

DON'T DO IT! Wichita KS is my version of the armpit of America. I lived there for 6 months and as soon as my contract at my apartment was up I couldn't get out of there fast enough.

It would be a promotion going to Wichita and it's closer to home than Florida

need some help...

so the guys who pulled my motor managed to break off the nipple on the back of the intake manifold that connects to the brake booster vacuum line. i went to the parts counter today to see if i could get one & they said they thought it was a molded part of the intake. is this true? can i just get that nipple somewhere or am i gonna have to take this whole manifold off & swap it out?

[banker099]
