I need to get an Engine ID tag made up, It's for a 64 1/2 289 power steering, no A/C.
Here's what I'm thinking it should look like:
Engine C.I.D: 289
Model Year: 65
Change Level: 1 (I assume)
Year of Engine Production - Month of Engine Production: Either 3-K, 3-L, 4-A, 4-B or 4-C (comments would be appreciated)
Engine Code No: ??? (Input Required)
I've attached a couple of examples, from the 65's I've noticed some variations...
1. first attachment has an N in between Production Date and Enginge Code No
2. What would the month M relate to? I assume the months started at A (January) and ended with L (December) - my fingers came in handy to help decipher those months, didn't want to get it wrong...
3. No Engine Plant Code (see last attachement).

Bob Mannel's book will give you a good breakdown of the tag codes, I don't have my copy with me but I can look some info up for you later if you need. I believe "M" was December as they skipped "I". Attached is a photo my my late June '64 engine tag, not pretty but original! Change Level "1" pertained to all 5 bolt 289's if I remember correctly.

Hi Greg, thanks for that, I knew I'd seen that pic somewhere before...
I do have Bob Mannel's book in front of me and you are correct that change level 1 is associated with the 5-bolt 289's.
From your tag I now know that 551 relates to a 289, and the book has a reference to 554 being 289 HiPo.
Did you figure out what N stands for?

Dom-
Going from memory, there's an appendix in the back of Mannell's book that gives more info (I think). The alpha letters that follow the engine code (551) relate to manual / automatic transmissions, which is which you'll have to research.

I'm thinking the "N" means engine plant code prefix. Attached is a photo from the Marti tag book.

Here's another photo for your reference. Finger there trying to keep the book from folding. Not pointing at anything in particular.

Yes, the appendix has further info stating that a:
Mustang 289 4V Manual trans is 550-B, and a
Mustang 289 4V Auto is 551-B (page A-6)
Yet yours has 551-C, so I'm not sure there...
I'm thinking the "N" means engine plant code prefix. Attached is a photo from the Marti tag book.
Thanks for those references
N - refers to the Draft Tube which is correct for Greg's 289
I'm unsure whether mine had a draft tube from factory as when I purchased it a 2 barrel intake was installed, I've sourced a manifold that doesn't have the hole but perhaps this isn't correct a correct application...
-
Does anyone else have knowledge regarding these tags or maybe someone has a 64 1/2 289 D code?
Not sure if it matters but the DSO is 71 (LA), would be nice to hear of other examples...
From the research I've done the tags looking something like:
-
"I've sourced a manifold that doesn't have the hole but perhaps this isn't correct a correct application..."
Dom-
I understood that if a road draft tube wasn't used, as in a closed system, in the early cars that a plate was used to cover the opening. I wasn't aware that 2 manifolds were used at the same time, one with and one without the opening. I'm not 100% sure, hopefully someone who knows for sure will chime in.

Here are a couple of pics of the manifold I sourced, it doesn't have the plate to cover the hole, however I have seen the type you are talking about, I assumed that a plate could be used if the draft tube was removed.

Found exactly what I was after in the appendix section, just need to change the engine code to suit transmission.
