My son just purchased a low mile 6.2l out of an airport tug to replace his original 6.2 of unknown condition. He has factory air on the original engine. We damaged the AC condenser when we pulled the engine out so that got me thinking about upgrading the AC system since we have to now replace the condenser. I've read about using larger pumps and a parallel flow condenser? Any suggestions as we live where is it routinely over 100 degrees in the summer and he does lots of in town, stop and go driving so AC is mandatory!

thanks!

I'd ask @AgDieseler. And if I were you, I'd ask the mods to move this thread to the garage section, where it will get a lot more attention.
 
Dave (agdeiseler) is running a vintage air unit.

Use a new parallel flow condenser & dryer, and a NEW, not rebuilt compressor. Should do fine.

Here's an current thread on the subject.

This is all true.

Vintage air is a good outfit, and it performs very well here in the Texas summer.

The largest standard pump available is the factory R-4. To go bigger would be custom mounts and lines. The popular Sanden swaps reduce the displacement but are generally quieter. The largest condensor that fits is the factory condensor. The parallel flow ones that are commonly cross-referenced to the squares are more efficient (per square inch), but smaller. They probably work a little better, but are also easier to plug. There are so many threads about A/C conversions on here and that's where you'll find most of the information. If you want to run R-134a you'll have to add condensor fans or something to get back to factory-level performance. The most powerful mod you can do to the system is use a different refrigerant.
