Hello everybody, I've been a lurker till now but I can't find what I'm looking for in the search. I've seen it mentioned that you can convert your a/c to an onboard air compressor and I was wondering if there was a faq somewhere or if somebody knows how to do it. Havn't been able to find anything conclusive on the site yet. By the way I have a '78 Trailduster Sport. I just put on a new RPM Performer intake manifold, a 600cfm manual choke Edelbrock Performer carb, Hedman headers, true dual exhaust goes straight from headers to flowmaster delta flow 40 series mufflers. I took off the a/c pump and the air pump isn't hooked up to anything. Then I saw somebody mention converting thier a/c pump to an air compressor and I couldn't find anything about it. So thanks in advance for your help.
