Not worried about gas milage etc right now, I have a truck for that. This is a test truck and lets test some stuff. The 5.3 is great I could figure out this surging crap. I already have a tire roasting set up, just surges in the upper rpms.
Looking at expanding the line up and see how it is already setting in the garage I figured I would try to make something happen over this winter.
We are looking at twin 76s or maybe a blower. It will be different thats for sure.
We have a 6.0L here as well but really want something different...
