Incorrect.That's a 65 model year for a 289 in a mid-size passenger car (Torino size).
Interesting 🧐 I know the K codes came with the same intake as any 289 4V, but is there a chance this one came off a K code ?Incorrect.
It was designed for the 1965 model year- C5. The Fairlane division was responsible for the design- O. It is an engine part- E. It is an intake manifold- 9425. It was the first version- A. It was cast at the Cleveland Foundry- intertwined CF.
The fact that the Fairlane division was responsible for the design does NOT mean that it was only used on Fairlanes- it was used on any vehicle that had a 289 4V engine. This myth needs to die.
The first line on the metal tag designates the engine it was installed on as a 289 built in 1965 to Change Level 6 specifications.
Yep, The Bob Mannel Book says 551-J is 289 2V for Mustang with automatic transmission. That engine tag and that manifold don't belong together from all appearances.551-J would be a 1965 2V engine, since it’s a 4V intake manifold I don’t think the tag is original to this intake.
The date code of 5B on the tag indicates February of 1965, I’m curious as to what the casting date code is on this intake manifold.
Trivia question regarding my 65 GT. I have a C6OE-9425-B intake manifold dated 5E6. Always thought it was the original, but I see it listed as a 66 model year manifold? Car was picked up at the dealership May 29, 1965. Thought the 66 parts were not on the assembly line until that years models was being built? Insights? Brian View attachment 840839
