so i've run into issues locating the correct parts for my 1971 302 which was installed in my 74 f100. the engine according to the people that picked it up at junk yard said it came from a mercury but they do not know which model. the casting code would indicate a torino but when i try to order distributor i am told it did not have a motorcraft (duralast) dist., which is what i have. the guy that rebuilt the engine said that the dist was what came in it and he did not replace it or the fuel pump.
i was told that one could identify the vehicle it was in by the serial number on the rear of the block. i have the number but can find no source in order to identify it.
serial number 1R210254 not sure if 0 is zero or O,, anybody got any idea where i could find the code in order to identify its origin?

 

There might be serialized numbers on that engine, but not a vehicle VIN. EDIT: Not the full VIN, see below.

Casting codes can not be relied upon as indicators of what vehicle the engine was installed in when new.

A '71 302 could have been in just about any Ford car or light truck. Most have that Torino/Fairlane code as that was the original target vehicle in the early '60s when the 221/260 were introduced.

What is wrong with your current distributor? If it's fubar, can you find an identical replacement?

 

The 1R210254 is the partial vin from the car it was originally installed in, year, assembly plant, and consecutive unit number. Your engine came from the 210254th Ford unit built at San Jose for the 1971 model year. If you really have to know more than that, you could always buy a Marti Report. Kevin could tell you what that unit was, but it won't be free. It really doesn't matter as 302's were very much garden variety back then and that engine would have gone into anything from Mavericks to Mustangs to Mercury's. (except Mercury serial numbers started with 5, so we know this one went into a Ford) The O in the third position in the casting number is simply an identifier of what division was responsible for the engineering. It has nothing whatsoever to do with what car the engine would have gone in. There's no reason why you couldn't ask for a distributor (or any other part) for a 71 302 and not get one that would fit. Find a new parts house. Try not to overthink this.

 

And do you know for a fact that it’s a 302?
Have you found the actual casting date on the block? I believe it will be near a flange behind the starter.

 

are you sure it's a 302? 71 engine code R is a Cleveland 351
it the posted number is the one hand stamped by the right front pan rail,thats the last of the vin number from the car or truck it came out of, casting number above the starter will also help break down what it is

 

Could that just be a coincidence though? With the typical numbering strategies for other Ford vehicles, that letter “R” just prior to the numbers, is part of the build sequence as well.
The engine code would’ve been one or two digits further up the VIN.

For example, on an early Bronco, a VIN would have read “U15GLQ*****” where the Q is indicating that it was the first group in the 73 model year. While a P was the last of the 72s.
Did the passenger cars use the same numbering scheme?

 

You guys missed what I said earlier. The stamped number on the engine block is a Partial VIN, meaning only the necessary digits are stamped, not the whole vin from the vehicle. The purpose is to identify stolen parts. With the year (1=1971), assembly plant (R=San Jose) and the six digit unit number, that's enough to trace back to the car if it was reported stolen, and the person in possession of said engine could be charged with possession of stolen property. The rest of the VIN identifiers are irrelevant. That's all there is here.

 

one km thinking of is a off a K code 289. 7 from the right is the engine . K hipo 289

 

I think Ford stamped the whole VIN on the early maybe pre '68 or so high performance engines only. I've seen one just like your picture on a late '64 HP 289 that I built for a customer. Right down by the pan rail on a non machined area of the block which seemed odd. I also saw a similar thing on a '63 427 that I built and that engine had it in more than one place, it was also stamped onto the back of the intake manifold.

Doesn't the partial VIN thing become federally mandated some time in the late '60's?

 

Yes, the early hipo cars had vins stamped on the engines to combat rampant theft. Hipo engine flags on the fenders was an invitation for loss in some places. The partial vin being stamped on all engine blocks and transmission cases was federally mandated in 1968.

 

I don't think we missed your point at all. In fact, our additions weren't even directed at your comment.
I was just commenting on the fact that I didn't think that the letter in front of the string was the engine code. Perhaps it is, because it's only a partial VIN. But perhaps it's the full end of the VIN build sequence code letter. I never said that all those other numbers were supposed to be there. I only used the EB numbers, in full, as an example of the engine code's and production number code's positions in a Ford VIN. I could even be wrong, if the passenger car VIN's were arranged differently than the truck VIN's?

The mandate in '68 must've been for passenger cars only at first? Broncos didn't have partial VIN's, except with seemingly rare exceptions, even through '77.
At least that's what I thought. Now I'll have to go back and look. Don't think I have the original '68 block anymore, and I definitely don't have my original '71 block anymore, but I do have a very early '72 Bronco block I can check.

But none of that really matters. Perhaps you can confirm whether or not that the letter at the beginning of the OP's VIN string is the engine code, or just part of the sequence code.
If you can, that would be great.
(Edit: never mind. I see you did answer that. In this case, the “R“ means San Jose assembly. Thanks for that!)

when i built that k code last year we had to use several numbers and factory markings to prove it, casting number, main cap size, rod bolt size, marking on the crank for testing hardness. screw in rocker studs , partial vin stamp, hand marked HP on the back of the block, we also found a stamping on the left rear of the pan rail of the day the block was machined, another in front that gave us the date of assembly,

for the OP it would be very helpful for him to post us some of the other numbers, every one he can find ,as i know this group of old timers will surely help him ,

 

Hey Charlie, sorry I missed the detail in your previous post where you showed the "K" right there in front of the serialized number.
Thanks for that.
Definitely be nice to see all the numbers of veteran2's engine.

wow awesome info and incredibly enlightening, gotta save it for future reference casting code D1OE-AA – 1971-1974, 302 Windsor small-block, 2-bolt mains
6015-AA OM1. finally out of frustration i wondered if it could be rebuilt so started looking around finally got a response from cardone and the info i gave them they said it was out of san jose could have been in a cougar, mustang or torino. the cougar rang a bell so looked thru paper work again, no mention anywhere. po's said from mercury manual transmission didnt remember model. only merc i could find from 71 with 302, manual on column and electronic ignition was cyclone every where i cked said cougar did not offer 302 in 71 so i dont know whats going on there. when i had contacted guy that rebuilt the engine as i was replacing the chinese carb with a1976 2150 and having issues he said could be distributor because it was the one thing he did not replace. well i thought he kept the dist that was in 71 engine but i contacted him today and he used the dist from the 74 the year they introduced the emissions stuff so i have been searching the wrong year all this time. turns out cardone has one with single vac while mine is dual sad i just obtained a nos dual vac for 71 302. trying to find a replacement pickup coil for it did not work, the one npd offers for 74-79 did not work at all.
when i got this truck the sent a guy from raleigh armed and dangerous to check the vin number, took 2 hours to uncover it stamped on the frame under a heap of hard grease. sometimes having fun is very hard work and at times stressful. thanks for all your help it keeps me thinking i can do this

 

A 302 is a 302 and could have come out of any vehicle Ford produced with a 302 as an available engine during those years.

Not sure what that would have to do with finding a distributor, other than perhaps it was changed out for another model (again, for a 302) from a different year, or even from the aftermarket. Got a pic of your distributor that we can see?
I think the only major change in distributors was the shaft diameter, but that was much later as far as I know. In the EFI era in fact.

Quite surprised you found someone at Cardone that would (or even could) give you that info. Nice to see someone willing to go an extra step for a consumer.
Not sure how they can tell where an engine was produced from the engineering number though. That would take the casting numbers that we mentioned before. The ones behind the starter.
And they did not cast engines in San Jose anyway. As far as I know, it was only an assembly plant.

What does 3-on-the-tree have to do with the engine installation, or the distributor?
Pretty sure the answer is, nothing. Maybe you can eliminate the manual trans shifter as part of your search criteria.

That's kind of surprising. But not by much since I'm not often surprised by the surprising things Ford did back then.
Rockauto does list the 302 for the '71 Cougar however. Although, they do not offer many parts and do not call out ANY distributor category. Hmm, could mean anything, but could also mean that maybe Mercury did have their own at the time? Weird...

In general, for Ford products at least (Mercury being the unknown for the moment) the only difference between a '71 distributor and a '74 distributor would be the older one would have points and the newer one would have had the Dura Spark type trigger.
Otherwise, there were umpteen variations with different timing advance curves, different vacuum advance configurations, and such. But the bodies were the same size throughout. Which is why you can convert a '71 points distributor to the wide cap of the '79 Dura Spark applications.
A few other minor variations in rotor and such, during the later years, but otherwise the physical fitments were the same.

Does it fit your distributor? My '71 points distributor had a dual-port vacuum advance and a weird thingy on the intake to make both work. I was looking for simplicity so I went to my local parts store and bought one for an earlier year of some kind that came with the single-port advance, and installed that on my '71 302.
Just because it was easier for me to tune, and because I hated the "idle hang" that the dual feed offered. When you would let of the gas, it would hang high for a second or two. Making it feel like I had less control over the throttle.
But all the parts fit, and worked (still work) together almost 50 years later.

Then it's not a standard Ford distributor from '74 or later. As THEY WERE ALL THE SAME BASIC PART and the pickup coil and reluctor wheel should mount right up.
Of course, if Mercury had their own, then all bets are off.
In fact, I think that the same pickup coil kit is designed to fit EVERY Ford distributor of that era. So even if it was from a 460 (which would not fit your engine of course) the coil would mount right up to the distributor.
Again, what does the inside of your distributor look like? You've been chasing down a part that might not be what you expect. Someone here is bound to recognize what you have based on a couple of simple pictures.

That's for sure! That's for dang sure!
So please do hang in there. But help us help you by posting some pictures if you can.

Thanks

Paul
