"068" Cam Question

I'm replacing the "067" cam in my 67 400 with the "068" factory spec cam. My car is a TH400 auto with A/C, power steering and power disc brakes. Will the "068" cam produce enough manifold vacuum to run all this stuff?

Yes indeed. The 068 is a very mild but effective cam. Smooth idle and plenty of vacuum.
