So I am now leaning towards doing a 6.0 LQ4 swap into my 75 suburban and for those who have done this swap or something similar, what have you done about A/C? Did you keep the LS A/C, keep the stock A/C or buy an aftermarket one, like vintage air?
For the squarebodies, I'd do Vintage Air. They have a kit made to fit that truck. The price isn't outrageous compared to replacing and repairing the original parts. And it's easier to fix than the factory setup.
You'd have to change the bracketry anyways to fit the stock compressor (since it mounts low and interferes with the frame rail) I think it would be easier in the long run to use a vintage air system. That's just my vote.
