[QUOTE="Doug's 73 Mach1, post: 409791, member: 7175"] For 351C engines 4V heads have "4" cast on a corner of the head next to the valve covers. 4V heads were used with 4 barrel carburetors, intake manifolds. 2V heads with 2 barrel carburetors, intake manifolds. If your engine has not been modified, the factory engine code is part of your VIN. It is a letter designation as the 5th character. That letter code can be used to determine what engine the car came with from the factory. Knowing the engine tells you weather it was a 2V or 4V from the factory. [/QUOTE]
