I want to swap a 6.0 Liter engine into my 1989 Silverado. I want to put a t-56 behind it. It already has a 350 and a 5-speed. If anyone knows where I can get mounts and possible advice it would be appreciated. Also, if anyone knows what modifications I would have to make to the new stock harness coming with the engine and computer to run the guages that would also be appreciated. Thanks.
