Just looking for some ideas/comments here.

I just got a brand new truck to throw an Ls9/6 Speed in it. This all was planned for a car but I decided to switch it up a bit on a new platform I don't have to spend years doing metal work on, plus I love the reg cab trucks (yes I know its stupid but that's not the topic ) .

The trucks currently a 2011 Sierra Reg cab 4x4 with a base 4.8L, 4 speed that would get ripped out.

I have a 05 GTO T56 but would probably sell that in favor of the Magnum/TR6060 if I went 6 speed.

I have a full wiring system for an 2010 E67 ECM from the engine, ZR1 BCM, Ls9 tank/pump, fuel controller/relay box, if needed.

We don't have to deal with emissions up here (yet) so I can probably hack that out of the ecm/fuel system.exhaust, etc.. Also, unknown if a zr1 fuel pump would work in the truck tank physically.

Would it be best to use the E67 or stick with the E38 in the truck. Will there be hassles with the ECM>BCM, ABS, etc communications with the vette E67, main concern being the cluster functions, on star, etc.
