I think it would do well. I have that cam in the shop 1-ton. It has power steering and power brakes.....vacuum is great.....it is a straight shift, however. It would be just peachy for the A/C with two things: (1) a '70's era adjustable solenoid hooked to the hot wire for the compressor clutch........I think Holley sells one that mounts nicely on the baseplate, and (2) about 500 rpm more slip than a bone stock converter. I have put this cam in 445's for pick-up trucks with C6 and used a stock converter, but both times they had 3.70-ish gears. I think the car could benefit from a touch looser converter and then you could run highway gears if desired. Might also put it on a 114 sep and smooth it up a little more. Would hurt the power just a bit, but would be smoother in a cruiser. I don't think an Ed head without mods would be as good as the N heads the way we did them. The BBM would like the wide lobe sep better than the stock head, and require less timing, but might not perform any better in this combo. The small cam and short duration might not get the good out of the BBMs. Some BP Pro Ports would be better than all other options, but really overkill and an expensive addition for not much gain in this situation. Below are some numbers from the dyno.

Stuska dyno with D-Pac data aquisition. This dyno showed me 626 hp on one of my EMC junkers and the contest dyno showed me 640 hp on the same engine. This dyno also showed me the same power as Jay's dyno on a Tunnel Port I worked on, so the numbers are legit, if not a little conservative.
