Help with Engine Casting Numbers. Is engine original?
Hello all. I'm trying to figure out if my engine is original. I've got a pretty clear photo of the casting number and I've looked at the engine casting numbers online but I'm having difficulty figuring out how to tie this to the truck itself to see if it's original.
Engine Casting Number is D1OE - 6015 - AA (Right below that number is a smaller text reading 1F22)
From my research online, that leads me to believe this is a 1971-1974, 302 Windsor small-block, 2-bolt mains. I do not know what the 1F22 means. And I don't know how to see if this is the original engine. Any help or knowledge is appreciated.
Immediately after I posted this I realized the 3rd digit of the casting is "O" which means this is an engine from a ford Fairlane or Torino. So not original. Oh well, now I don't have any reason to keep it original.
Idk if the mods can delete this post or not. It's unnecessary now unless someone is interested in double checking my work.
The casting number will tell you what car line that block was originally designed for, but not what vehicle your particular engine was originally installed in. That information is only found on the tag attached to the one of the coil mounting bolts on the intake manifold, and unfortunately they usually wind up getting removed, especially if the manifold is changed out for an aftermarket part.
I would say it’s potentially the correct motor. Fords generally don’t have “matching numbers”. Should also be a date stamp when it came out of the foundry, which is also only helpful if blatantly incorrect for the era.
That 1F22 is a casting date. June 22, 1971. If your truck is a 1972 that would be about right because it would have been cast a month or two before it was machined.
If you look on the rear of the block on the driver's side just below the cylinder head, there are some numbers stamped into it. Those numbers should match you truck VIN. These numbers are about the only way to tell if the engine is original. The transmissions were also stamped on the top side. The insurance companies forced the auto makers into this around 1969 or 70 because there was no way to trace stollen parts before that. Those numbers are not heavily stamped, so you have to look closely and read them in a mirror most likely.

I’ve heard that and never seen it. I have a 73 302 block sitting around, can’t locate any vin stamp.
These numbers were hand stamped and were not deep or easy to make out. If they aren't there either you have a service replacement block or the guy doing the stamping took a day off. I'm sure that a bunch of engines got out of the plant unstamped since this was something the insurance companies wanted because chop shops were in their heyday at that time. This is a 71 351C you can see how lightly they are stamped. Just the paint alone will fill them in and make them unreadable.

My intake has a casting number of D30E-9425-AA. This was the first thing I found that made me think the engine wasn't original. If I'm reading it correctly that means the intake was made in 1973. But that's close enough to the truck's production that I'm not sure it proves it's not original. It also could've just been the intake manifold that had been replaced at some point but I feel like it would be rare to only replace the intake manifold. I didn't get a chance to look for those other numbers. I'll try this weekend.
Not the entire VIN just the last 7 or 8 numbers and letters. The transmissions were also stamped with the same number.
where exactly is that? I am lookin at a d4de block, casting may be a bit different. I can’t locate anything. I have two more 302s sitting in econolines that I should be able to see also. Have checked one, I didn’t find anything.
also have the c4 that was bolted to the d4de. Would really expect to see the stamps in aluminum, can’t locate anything.
looking like a lot of days off or replacement drive trains.
They are usually stamped just below the deck surface on the driver's side rear of the block on V8's. Sometimes that is a machined surface sometimes not. I've never been able to make one out with the engine in the vehicle. I have read that they were also stamped in other locations but all the ones I have seen were on the rear of the block. The transmission was usually stamped on top at the back near the tail shaft housing. This block was cast Oct 1970, 351C, 2bbl out of a station wagon you can see they weren't really neat about it. The only trans I have out is this 1987 C6 out of an F150.
