85 crew cab 5.3 or 6.0 swap

Yes, and yes. I'd strongly recommend a 4l80e or 6l80e trans instead though.

Yes I would like to have overdrive thought may be hassle to wire?! I'm not to good at fabricating so do they make kits for motor/tranny mounts?

Wiring would be easier for the motor designed for the engine... you can basically drop the whole thing in and plug it in using a modified factory harness.

The aftermarket harness can be built with the plugs for the 80e
