That's your problem.

It will not work with the 03 up system for the cluster and everything else.

You will have to change the red connector to a green connector from your old harness and re use the original PCM. It will then need to be re flashed for a V8.

Or Re-pin the V6 harness by adding the injector circuits and reflash the computer for a V8

Ohh that makes sense what would you think it's the best thing to do and takes less time

Remove the red covers from the PCM connector and install the green one's would be the fastest/easiest. I would have to look at the Pin outs though to see whats different or changed between 01 and 03.

Then you just need an operating system that uses a mechanical throttle body. There were some that retained the mechanical TB and I know for sure a Van would have that.

Can someone help??? I have an 2007 classic and having issue mounting up motor mount to frame. one side mounts perfect and other side is off by maybe 1".

You have the wrong frame mounts.

Coil Spring Frames and Torsion Bar frames are different and have different frame mounts for the engine mounts to bolt to.

OK so what exact engine mounts and frame mounts do I need? Original post is vague and my dealer is retarded and I'm close to that haha.

This is a 4.3 to 6.0 LY6...

Any help would be appreciated. Tried searching but can't find part numbers...
Truck is a 2003 2wd and engine is a 2008.

Are these the 2 brackets I need?

GM 15113848 and 15113847???

edit; Ordered those above part numbers from the dealer with my discount.

You did not state if you are coil spring or torsion bar front suspension.

15113847 RH appears to fit both

15113848 LH appears to fit Coil spring frame
15113849 LH appears to fit Torsion bar frame

Someone please correct me if you find out other wise.

Sorry, I have coils up front.
