I have a 1992 4.3 and I'm looking to put a smaller belt that doesn't use a/c or the smog pump, compressor doesn't work and I'm planning on replacing a while down the road and I've heard a lot about smog pump just not being worth keeping and I'm wanting to get my engine as efficient as possible right now before I do serious work on it. Any help with alternatives or part numbers? It would be the same as if it was done to 5.7 of the same year
