273 Commando with Hydraulic Camshaft

stock 340 is very close (same) to the stock 360-4 cam through most of the years. I picked up a 360-4 out of a camper special W150 and it had this 340 spec cam in it. 340 auto spec cam was pretty mild. It was used in the police 318-4 motor and those idled for days with all kinds of alternator load on them
