Thanks for all of your help. I was starting dinner when I posted. I just returned and clicked edit and added spaces before I saw your post.
No prob, hope it helps.
BTW I want to explain something I already explained to Justin (AB) that some of you guys may be raising one eyebrow in a Spock-lie fashion at....
Specifically, look at the information given for 1980/83 engine blocks:
Notice it says for MY 1980 through 1983, use a replacement engine block with an E7 prefix.
This means that, during the 1980-86/7 time period, the block used for 1980/83 engines either 1) Went through revisions, or 2) Was combined with a block used in later years.
In either case, Ford eventually came up with one replacement block to use for all of 1980-86 engines (yes, I see that E4 1984/85 thing, but notice how it's obsolete and and was replaced, I would guess by the same E7TZ that all the others use but I don't know how to look up that "mat # 85051" code to verify that).
It looks to me like they eventually came up with one block to use for carb'd engines, and one for EFI.
Point being, Ford didn't design a 1980 block and give it a Casting ID with a date in the future.
BTW my M-block, in addition to the Casting ID and Casting Date codes, IIRC it has an Engine Assembly date stamped elsewhere into the thing, I think right by the timing case cover.
This is wholly separate from the other codes.
I would have to assume the 6-banger also has that somewhere but I wouldn't know where.
Hi, New member here. Not sure I'm posting this in the correct location. I have a bitza 1964/1965/ pickup. (bits of this and that from here & there). It has two different vins that I'm working out with the California Highway Patrol. The reg & title belong to a 1964 drivers side door warranty plate but nothing else on this truck..
I Finally figured it's a 1965 twin I beam from the chassis vin.
When new it had a 240, "J" engine code.
I Measured the stroke down the rabbit hole and found it to be a 300 (almost 4" stroke).
The numbers forward of the starter are "D1AE-8015-CA OK fomoco"
The 8015 may be a 6015. My 72yr old eyes are fading.
After reading these thread notes it appears to have been cast Oct 1970 .
But the A instead of a T means it was not a truck 300??????????
The block and head are painted red and it looks to be original paint.
The pan is ford blue. Valve covers black.
Beneath the passenger side motor mount is a very large C with a capital F inside the C. There are other marking there but I can't make them out.
Many of the intake manifold tabs are broken off.
I'm surprised it doesn't suck air.
It idles fairly well/165psi compression each hole.
Any thoughts regarding identification of this engine?
Thanks in advance for any help.
