    title says it all, hasn't someone done this? thinking my OBA setup might be easier since I would only have to mount the compresser in a fixed position and the idler/tentioner would take care of the tention issue.

    well you could but by the time you bought it all from thw wrecking yard it would cost more for the used stuff than it would for the new right out of the box /forums/images/icons/smirk.gif i have priced it out once already...it was goin to be in the 600+ area if i got it all used...

    I don't know how it would bolt up but there are a ton of 88-95 trucks with serpentine systems that I would think you could get cheap. This may be what Chaz was talking about being $600. I dunno. I've seen this in trucks before but I don't know if they swapped the whole motor or just the belt system.

    Anybody try the setup from the 4.3 v-6? It looks like a direct swap except for the crank pulley. I was quoted $50 for the brackets and pulleys from a 4.3. I think I can get it with accessories for $100 or so...

    Should work in theory, from what I've heard, (you know how that goes) it's all the same on the front end as a v8

    Wow I never would have guessed that much. Our yards smash everything so quickly or they stack them on top of 20 other cars. The 4.3 is the same with 2 cylinders cut off the end so like said in theory this would work.

    the local yards in stockton are basicly picked clean...so for anything worth buying i have to go up to the yards in sacramento...and most of them up there wont let you take the parts off yourself...you have to pay them to pull it off...thats why its so expensive /forums/images/icons/crazy.gif

    Vintage Air in San Antonio makes a serpentine belt drive kit. I do not know the cost, but it looks trick..
    www.vintageair.com
    Or do like I did and install a later model TBI 350 and get the serpentine drive and new compressor for free.... /forums/images/icons/cool.gif
