    5.3 overheats when going up mountains. Any ideas?

    I’ll lose almost 1.5 gallons of coolant when going up mountains. I have a 5.3, 4l60e with stock v6 gears. I think 273s or something like that. Anyways, any ideas? Could it be that my rear end is pulling my motor abdctrans down? I have a 1k treck back home and I’d like to make it.

    WONDERING WHICH COMPRESSOR I SHOULD USE AND AC SET-UP

    I'm new to this forum, so bare with me. I have an LS swap in my 83 Cutlass Supreme. What is everyone using for their AC setup?
