    so i got all the stuff from a newer sbc to go serp. on my 79/86/77 abortion...

    it has an a/c compressor, and i will not be running a/c... should i make a plate to cover the outlet and inlet holes and oil it and just run it? or should i get a shorter belt, and which belt should i get? any way to tell what year this setup is off of? i got it from a friend who it was given too off of a newer sbc...

    You could leave it in place and use it for onboard air, or buy an "a/c delete" pulley that takes its place. Blocking off the ports works just fine also, just to keep it from getting ruined, should you decide to use it later. :cool1:

    It's not going to lock up on you if you don't block off the ports, it's freewheeling when the compressor is not engauged. All that will happen is in time it will basically make the compressor unusable for A/C.

    when i say freewheeling, i mean the clutch,, no power to the clutch, and it won't engauge the compressor.

    I'd still see about aquiring the A/C delete pully though in the future

    Yep, a friend of mine has had an R4 style compressor for OBA on his TBI 350 powered CJ7 for 8-10 years. He just drips a few drops of oil into the intake side every once in a while.

    kinda of a useless point, as i mentioned previously, the compressor does not spin at all unless the pressure valve sends power to the compressor (switching on the ac) all that is going on is you are freewheeling the clutch, which there is nothing to oil.

    Hell, technically, i have been running mine like this for the past two years, as i haven't been able to get the ac working properly, and sort of gave up on it :crazy:

    Pay attention to the thread... :doah:

    He asked if it was OK to use the compressor for OBA. The answer is yes. You're the only one harping on when the compressor actually engages. :rolleyes:

    Just bear in mind that you can't 'mix and match' all the serp stuff. GMPP serp set up is way different to stock K5 serp stuff.....ask me how I know!:rolleyes:
