I'm new and not sure how this works, or whether I am breaking any forum rules, but I have a question. Can anyone help me with an engine ID issue? I have a 1966 correct craft mustang with an interceptor engine - not sure if it is the original engine. Engine serial number is ra1r318025. Can anyone identify the specs/year from that? I am having problems buying parts and am thinking it is a vintage issue since none of the parts that are supposed to fit actually do. Thanks in advance for any help.
