I am in the process of doing a V6 to V8 swap in my '04 Silverado RCSB. I am looking for the motor mount set (cross member and motor) and also the wiring harness for a V8 Manual trans setup. this would really help me going.

Thanks
Nick

 

I have a V8 harness for a 04 (drive by wire), but its for an auto. Let me know if it would work.

 

Thanks but from what I'm understanding the auto and manual harnesses are different at the trans

 

pm on motor and frame mounts sent.

 

You could probable re-pin your trans harness into the PCM harness at the PCM plug if you get the pin out diagrams. I have a felling your going to have a hard time finding a manual harness as they didn't make many trucks with a manual. But either way, if you can't find one let me know.
