Is there any difference between the oil pump and timing gears and chain for a 1964 318 'A' engine versus a 318 'LA' engine? Just wanted to know before the mechanic that is going thru my engine replaces it with maybe the wrong one. Also are there any other noticeable differences between the 2 engines besides the valve covers?
