I own a 87 fiero 2.5 duke all stockengine, if I remove the engine for an overhaul can I keep the ac refrigenate or will I have to disconnect the hoses and do the ac over?

Sure just take the ac compressor off the engine and leave it in the engine compartment while removing the engine.

When I dropped the cradle on my 88 duke recently (to replace the throw-out bearing), I just disconnected the AC hoses. Then when I got it back together, I pulled a vacuum on the system and re-charged it. It works fine. However, if you haven't previously converted to R134a, and want to keep R12, it would be better to remove the compressor and leave it with the car.

I don't think the hoses are long enough to get the compressor off, with the hoses still attached on a 2.5 . the compressor (On mine), is mounted onto 2" long studs that the compressor must slide forward on to come off.

Well yours is special,... err I mean different, no studs normaly.

Yes just unbolt the compressor and hang in as not to stress the lines(IE tie a string/wire to it and tie it off to the deck lid hindge bolt, so it hangs at normal height), then pull the engine, as you pull it keep an on the compressor, just to make sure it doesn't snag.
I have done it many, many times.

Lou, the engine didn't come with studs as a part of the block, so they can be removed. If there's enough threads exposed above he standard nuts, thread another nut onto the end of the stud. Hold the original and tighten down the extra nut. Then loosen the original nut. The jam nut will allow you to turn the stud without removing the nuts. The stud should come out so that you can leave the compressor hanging in the car.
