I am completely a/c ignorant. I removed the stock chevelle a/c system prior to the engine swap but kept all the old parts. There was something wrong with the stock stuff as it was freezing the line near the evaporator.

I also have an LS compressor and bracket but I don't recall if it is for Fbody or Corvette accessories. Either way I prefer to use a stock LS type bracket and compressor so I can round up what I need there. The car has Corvette accessories and a Powerbond underdrive pulley.

I have all the old chevelle parts, but it's my understanding it might be better to change to evaportator out for one meant for a newer system that doesn't use a POA valve. Someone in a thread mentioned a 3rd gen camaro condensor?

Might need to have lines made to join the older system to new compressor, this can be done locally I'm 99% sure.

I'm using a 0411 LS1 PCM and factory harness. Fairly certain the a/c section of the harness is in tact, if not I could repair it.



So I guess I just really need to know what is the best/easiest way to get this stuff working? I'm reading a lot of conflicting opinions on using full stock chevelle stuff aside from the compressor or mixing and matching parts and it's making this seem way more complicated than I think it should be.

Any insight or point me to some reading that's more straightforward?

You'll need to use a fixed displacement compressor, so that means a truck compressor as-is, or a F-body or Corvette compressor that has had its displacement valve removed and modified to lock-out variable functionality. Converting to an orofice tube/accumulator configuration would simplify the system greatly.

Are all the ls compressors interchangeable in the bracket?

Like, could I just get a truck compressor and install it into the Corvette bracket?

Toddoky

No, they each use their own specific bracket and install at different fore/aft offsets to match the accessory drive.
