Hello - recently had a NOS 305 V6 cam reground (more performance) for a freshly rebuilt 351E - I understand that the camshafts are all basically the same as far as where the dowel pin is located on the cam Correct? - OK now in 1966 (my motor year) the factory changed the position of the key way in the cam gear in relation to the dowel pin on the cam - which would change the timing of the crankshaft and camshaft - my engine shop assembled my motor and had the front waterpump housing on - I NEVER looked at the timing gears to make sure the marks was "straight up" or what gear set it has - earlier or later - THERE IS SOMETHING WRONG! - engine will barely run with ingition timing at 35 degrees advanced - anything under that it dies after it coughs gas out the carburetor - I'm thinking crankshaft to valve position is OFF - I'm thinking wrong cam gear set. What gear set should I be running or am going looking at this wrong? NEED HELP PLEASE - Thanks in advance!
