Hi guys, ive been thinking about adding A/C to my 57 and doing so with the Vintage Air Complete Generation IV sure fit kit. Has anyone installed this kit? Any problem? I hav a 283 with a mild cam, will the cam be a problem? Thanks!

The VA kits are pretty high quality and are the "standard" for A/C imo. You can choose either the 4-outlet version or the under-dash one. I went with the 4-outlets to fit my custom valence. I don't see what a cam has to do with A/C but maybe I'm missing something.

It may mean replacing a single belt harmonic balancer pulley (crank pulley) with a “dual belt pulley”, since you’re adding a compressor to be bolted onto the front of your engine. Not sure if that comes in the kit or not, but once you have this system installed and working, you’ll never go without AC again. The Vintage Air systems are a solid improvement.

Thanks guys...Hopefully i'll have a/c in my 57 by next summer!
Yes you are, a HP cam typically has low vacuum and rough idle quality. This was why on my 74 Z28 the second year AC was available on Z28s it has a solenoid that bumps idle speed when AC is turned on. Without it the relative smooth idle at 900 rpm with clutch in goes to hell. The 73/74 z28 had a high lift hydraulic L-82 Vette cam where earlier Z28s had a solid Duntov that would have never supported AC.

I had a mild cam in the 350 I built for the 9 passenger, and when the AC is turned on, it does pull the rpms down a 100 or so...
But it was never a problem...I doubt he'll have a big issue with a 283.

Doing an EFI conversion so that you can have a/c on a 283 is ridiculous!
Shame on you Chevynut by potentially misleading the OP.
