Before the l83 6l80 upgrade in my 87, it had 5.3 4l60e and the compressor fit zero problem. I dont remember what i did exactly for ac lines, you can search my build... pretty sure i used generic adapters and just crimped ends to hose and bolted it all together. Bought the crimper as it was cheaper and easier to do it myself.... brazing aluminum ac lines is different. The suction line i did notch the frame, but more custom hose can avoid that... even then it was a quarter sized notch. Again, search my build threads to find the fitment pictures.

The l83 was tighter than LS and with my experiences i made it fit with plenty of room, even welded the notch back up
