Hi folks. I posted this in the '48-'56 forum, but it was suggested that I post it here too. So here goes: Hopefully somebody here can help me identify this y-Block. I've always assumed it's a 312, but now I'm quite sure it's not and suspect it MAY be a mid-fifties 332 Lincoln/Truck engine.
Here's the scoop: The truck is an olive green 1963 Flareside that according to the VIN was originally a military truck, and at some point it ended up in the fleet of the University Place, WA School District. I bought it from a knucklehead who was going to scrap it if I didn't buy it, because he couldn't get it running. Needed a carburetor.

My running theory is that the crew at the school district got bored one summer and decided to swap out the drivetrain from a schoolbus and put it in this little truck. The transmission is a granny gear 5-speed (1st gear is right and back, reverse is right & forward. No synchros)

I've had the truck a few years, but never driven it much since it gets about 8mpg. I am planning a bit of a restoration on it before the rust gets too far advanced, and was thinking about putting in a more modern 351 with GT40 heads and a T-5, but the more I think about it, I think I like having the old skool drivetrain, and cleaning it up a bit. But I need to know what gasket set to buy first. And maybe even what color it should be!

After spending the last couple days trying to figure out exactly what this thing is, I'm hitting a bit of a wall. None of the internet photos seem to be a match. Many are close, but things like exhaust or intake manifolds or water necks seem to differ. The casting numbers I can find are not much help either. Above the right of the oil filter (where I thought a casting # should be) is a pretty large X. To the left of the filter and near a freeze plug is a casting that appears to be OM2974 (as seen in the last photo). But that number yields no results for me. This is a Cleveland Foundry casting, as evidenced by the CF mark near the distributor. Thanks in advance for any help!

And a photo of the truck. Just because.

 

I'd say your correct based on this engine.
Lincoln 317 Engine Y Block with 4 Speed Transmission and Transfer Case | eBay

I am more of a GM guy and I thought it was a Caddy 390 at first.

 

Yeah, that's a 317 on ebay. It has a 2 barrel intake. I wonder if my 4 barrel square bore intake suggests a particular CID.

For the benefit of future researchers, this is one of the photos from the ebay listing above, which pretty clearly shows the casting numbers. Mine is shown below that, with simply a blank boss in that location.





Also, I thought I might glean some info by looking into the tag on the distributor, but running the numbers on that don't even give me any clues (except that I can upgrade it with electronic innards)

 

is the carb a 4v?
I would like to see more pic of this baby very interesting

 

It's 0M2974 - probably the block casting date code: December (M) 29, 1960 (0) / A = January, the letter I is skipped / 74 might be a code for an engine assembly plant.

The valve covers are a dead bang give-away that this is a Lincoln or Lincoln derived Y block.
-------------------------------------------------------------------------------------------------------
More than likely, this is a 302 or 332 Lincoln derived Y block originally installed in: 1957/63 B/C/F700/950's / B is a school bus, C is a tilt cab.

If the C3TF dizzy is original to the engine, it's from one of these 1963's / C = decade: 1960/69 / 3 = 1963 / T = Truck / E = Engineering

ID number: C3TF-12102-E = Ford part number: C0TZ-12127-F .. Distributor Assy (Auto-Lite/Motorcraft DA-540).

Left (scroll down a bit): 302/332 parts catalog applications / Right: Cross reference: ID # C3TF-12102-E to Ford part number: C0TZ-12127-F

 

Damn cool truck

 

Thank you guys. Number Dummy, just to clarify, it's C3TF, not C3TE. But even though my eyes are rolling back in my head after reading through those pages, I don't think that changes much of anything. BTW, I've followed this site on & off over the years and the wealth of info you bring to the table is overwhelming. Thank you for your dedication.

Schoo, yes, it's a 4 barrel iron intake for a Holley style mating surface.
Got my eye on an old Hilborn setup on ebay right now but after thinking it through, I think I'll leave the 4 barrel in place for now.

 

I typed the F as an E .. cuz I didn't pay attention.

But, I posted two pages from the '57/63 Ford truck parts catalog that list the dizzy ID number as: C3TF-12102-E

 

Yeah, I saw that. And wouldn't you know it, I put a timing light on it today after rebuilding the carburetor and the distributor is not advancing. I'm afraid I know virtually nothing about these non-vacuum advance units other than how to change the points & condenser. (I was born in 69)

 

I don't know much about them either, don't recall owning a truck with this type of dizzy (I was born in '44, when FDR was prez).

Parts catalog ID chart for C3TF-12102-E = refer to illustration section 120, page 757. But there were two other types of dizzies used in these trucks. Wanna see pics?

 

Ha ha, you're awesome ND. Sure, I'll take a look.
Ya know, even if this engine isn't original to the truck, they made it look like it is, which is pretty neat. Even the distributor tach drive cable works with the dash mounted tach (although it redlines at 3500! thankfully there's no rev limiter!)

 

What do you suppose those parts are are below the advance weights? 12459, 12493, and 370596-S? I noticed the footnote says there is a governor. Never noticed that before, but do you think that's what those are? Does the governor simply limit advance or does it actually prevent a certain rpm from being exceeded?

 

The 302 and 332 are definitely "Y" blocks!

 

They are both built with low compression and have timing gears for reliability.
