Most older vehicles a/c compressor will not last at 6500 RPM's. In the late 60's the muscle cars (GM) with the solid lifter engines and 6000+ RPM levels did not offer a/c as an option.

I took mine off of my 86 GMC to save space, etc. I will not use it since in the summer I would rather hear the exhaust sound. An older a/c compressor probably eats up about 15 HP in my opinion.
