Ok, I've got my hands on a low mile 99 5.3 engine and solid plans are to drop this into my 94 k2500 4x4 that currently has a 350 tbi/4l60e with 183k plus miles on it.
I'm in the early stages of this swap so I want to get some of the simple details out of the way and some general rumors cleared up in terms of the tech side of this swap.
1) Motor mounts....5.3 to OBS....S&P makes these correct? If not who does? Anyone got a part number or price? I did not see anything on S&P's site regarding this...
2) I am considering using a Painless Wiring harness for this swap and from what I've heard and seem their harness has 4l60e trans control built into the harness. Is this correct and if so will my 94 4l60e work? I am unsure if the electronics are going to be different in current 4l60's vs. the older 4l60e's.
3) I would assume my stock radiator and trans cooler will be adequate for this 5.3....I will be upgrading my stock trans cooler with a secondary one soon so I'm not worried about that. It appears as this 5.3 has oil cooler lines so I will add a oil cooler as well. Anything I'm missing?
4) Do I actually need to find myself a 99 brain or will any 99-04 brain work with this 99 engine. I figure any one for 99+ should work since I'm not really using any stock wiring....any confirmation on this?
Any other tips or things I need to immediately concern myself with here?
