73-87 V belt setups - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 77 with the huge Harrison log compressor. I recently took it off because the system had no freon left and my valves were in desperate need of adjustment. Removing that valve cover with the compressor in place would not be possible.

I'm now seeking a belt/accessory setup that's going to give me plenty of clearance to run a tall valve covers and take them off at any time with ease. I know an early 90's serpentine setup will give me this, but it just wouldn't be cost effective at this time unless I got an extremely good deal on it.

What about the short/fat A6 compressor from the 80's ? I've seen some trucks that use this compressor with a V-belt setup. Does this compressor and bracket setup interchange with the 70's V belt setup ? Will the brackets/compressor/lines obstruct the valve covers in any way ?

On my 79 with the Harrison, all you have to do is remove the bracket that goes over the valve cover. It's kind of a pain, but I love my A/C. I suppose you could adapt the shorty compressor to work, since your system is already apart...

My setup cost me $250 with everything ac compressor, bolts, power steering, alternator and all the pulleys and tensioners.

Thats the setup I want to get. It's just tough to budget that in right now. I had a Chip Foose kind of vision for my truck this summer but ultimately I have to prioritize and get the engine and transmission swap done before school starts.

I was just wondering if that short/fat V-belt compressor is compatible with the older V-belt setup from the 70's that used the huge log compressor. Also wondering if it provides good valve cover clearance and convenient access.
