- 71 M code, light pewter 4 spd. ram air, no stripes, no spoiler, deluxe or sport interior needs compete restoration .
Hello all. I am putting my 1971 M code 351c together and noticed my 4v closed chamber heads had the casting numbers of D1AE-GA so I felt they were probably replaced through the years. They have 0J4 and 0J8 date codes. Which if I am correct means 1970 Sept 4th and 8th. My question is were D1AE heads being produced in 1970? My car was assembled in October of 1970 so I wondered if they could be the original heads. I guess my thinking is they should be D0AE heads to be original. Can anyone educate me on what I have? Thanks in advance...Bryan
