I have posted here before but it has been a while...

I have been stationed overseas for the past two years and have not until yesterday seen my jeep for the same amount of time. I say jeep, because it is a 81 cj5 with some ford engine in it. I have come to the "conclusion" that it is a 351 but of what sort I do not know.

I just went out and looked at it and got all the numbers off it that I could as well as snapped a few pictures for my following (obvious) question.

I have no clue what engine this is!! I am ford engine illiterate.

I got two sets of numbers off of the intake...

From the front of the intake the numbers I read were: 37266543 12

And from the rear of the intake I read: 4021 D30E 84258

I am not sure if the numbers on the intake mean anything but there they are.

From the bottom of the engine I read: D4AE 6015 DA4, which was located right on the block at the starter.

I remember hearing/reading that the way that the coolant enters the engine makes a difference with the models. On my engine the inlet is not a 90 degree elbow it just goes straight into the engine...

Few pictures for help....



And one for the crowd...

 

I'm seeing that number above the starter translating to a '74' 351. One way to tell the difference between a 302 and the taller 351 is by looking at the distance from the front cover top bolt to the head surface, shown in this comparison between the two blocks, red circles

The intake on a 351 is roughly 1" wider then the 302, he is correct D4AE translates...
D='70's
4= Fourth year of the decade (so 1974)
A= Galaxy/Fullsize
E= Engine Component

The casting numbers on the intake would indicate

D= '70's
3= Third year of the decade
O= Torino/Fairlane
E= Engine Component


So if you put that together you get a 351 2V from a 1975/6 Torino (The only 2 years the 2v 351 was available in the torino, Fairlane ceased production in 1970)

This would be my best guess anyway... :-)

 

Problem is that the block casting number only tells you what that block was designed for, not what it was meant to be used in. Mustang never got assigned a letter and look how many of them are out there. They had the "A" that would show the Fairlane because that is what the motor was designed for. That motor could have come from many different cars. You've supplied some added info, didn't have the intake numbers. Think I have learned over the years is that in so many cases, parts have been so interchanged, hard to tell what's original. I had a "K" code Comet that was only rated at 210 hp, ever heard of them?

according to the sticky the Mustang got the letter "Z"

As for the K-code Comet, according to wiki...

"A high-performance version of the 289 engine was introduced late in the 1963 model year as a special order for Ford Fairlanes. The engine is informally known as the "HiPo" or the K-code (after the engine letter used in the VIN of cars so equipped). Oddly, this engine was introduced in 1963 as the only 289 engine available in the intermediate Fairlanes. Lesser powered cars had the 260 engine in that year. Starting in June 1964, it became an option for the Mustang. NOTE: K-code Mercury Comets were the 210 HP 4 bbl carb engine not the High Performance engine as the K-code Fords."

 

Yep, you and the "sticky" are right about the Mustang getting the "Z" but that didn't happen until the real early 80's I believe and never seen it on an engine block casting.
