Selecting cam to work with A/C
I don't see why that cam shouldn't work. Surely you won't be running with the compressor on up to 6500 r's on a regular basis.....right :). Nudge the idle speed up a hun or so and you probably won't notice it. Easy with the 4spd.
I would make sure your cooling system is up to snuff. Hanging that condenser on there won't do you any favors.
