I just finished my ls swap in the 1968 suburban. If I was to do it again I would mount the pcm to the core support on the drivers side using the express van mount. The pcm will not fit under the battery tray on the drivers side it will fit on an angle beside the battery using a aux tray but it takes alot of time to just make it fit. I would use express van cables for a factory look keeping the battery on passengers side .

Air intake I would route to drivers side using a custom intake tube.

I would never use another rad with outlet and inlet on the same side again. its just stupid. My hot rad hose runs along my cold air intake that goes towards the passages side. The idea of a cold air intake is totally wasted with the tube running along the hot rad hose.
