Was A/C ever an option on 340 six Pack cars?

The only way it was different is that it was ground as a low taper design to be lower friction than the standard Commando camshaft. It had the same specs, though.

Exactly, plus it was a 3 bolt instead of a 1 bolt sprocket.
I said it was different but not in what way. So there you go.
