Ok I've bin saving up for this for some time so it's going to happen, the motor I'm going to drop in will be one of three 3116 3126 or c7 any help on witch one mite be better I'm leaning more toward the 3126 for the price and availability and no I'm not going with a cummins or any thing els I'm dead set on the cat and I'm going to make it happen

Next is the truck it needs to be 1997 or older to get around California smog, also looking for a 1 ton any make as long as it's the big three I need help to decide witch one would have the biggest engine bay or best front end to deal with the weight not afraid to break out the tools to make it work

Tranny I'm looking for a 6speed I can have an adapter plate made for most anything so witch would be best nv5600 zf6 or other any ideas I need them

Motor what ever I get won't be stock when it goes in, the guys at the cat dealer are all for helping me getting some thump out of it, I'm thinking if possible with a cat head studs,o-ring injectors, twin turbos, injector pump, I need ideas if needed I can have some custom parts made.

Before I jump all in I need to be fully ready so let's hear it some info so I can get the parts and the torch going
