Hi, I'm new to this forum and new to the world of owning a antique truck. I recently bought a 1954 F100 with a 239 Y block, along with it I received a 1954 F100 parts truck. I am trying to identify what year the motor and trans are in the parts truck and wondering if it was pieced together or did it most likely all come out of the same vehicle. I know it is either a 292 or 312 but no idea what year, any help would be appreciated.
Engine ECZ 6025A
Transmission AF 7006 D 21 (16 spline on the back end and no tail that I can see of) bolt pattern of trans is 7.5" tall x 5.25" wide. has side cover with 9 bolt. looks like a 3 speed
Intake manifold ECZ 9425-A
Carb Carter WCFB

Thanks

 

Welcome to FTE

See if this helps. If not there are other sources we can try.

Y Block Identification

 

Lots of info here:
TECHNICAL

 

That's the same page link, isn't it?

 

Yes, note the time stamps on the posts. I was right behind you and didn't see your post. OP can go there twice, get 2 times the info.....

 

Thanks for the info, per that it's a 56. I still wonder if everything else is a 56 also.

 

One thing to keep in mind, the 239 is a different animal if I recall correctly. There isn't anything "wrong" with it, but some of the parts are getting harder to find and/or not interchangeable with their bigger brothers like the 292, which is more common. And 292 parts aren't exactly laying around in the ditches for easy pickins like some engine families.

I'm going from memory, but it may have what's called a Loadomatic distributor. These were a short lived design, that used engine vacuum exclusively for the ignition timing, coupled only with a proprietary carburetor design to supply two different types or sources of engine vacuum. What this means, is no other type of carburetor can be used with this distributor, or it won't run right. Some people say they don't run right even with everything setup according to Hoyle.

Post 1956 ignition distributors are conventional mechanical advance w/vacuum advance, aka "dual" distributors, but they use a 1/4" hex oil pump drive shaft, and a different number of teeth on the drive gear, unlike what you have now. Not trying to discourage you, just illustrating why a 239 isn't first on the list for restoration or hot rodding efforts.

Just a FYI, study up on them before spending any money or picking up parts. A compression test and other diagnostics would be my plan. A 292 should drop in and would be a better choice if rebuilding or replacement is warranted.

 

Thanks for your feedback. My current plan is to hopefully keep the 239 that is in my good truck running for now while over the next couple years I rebuild the 292/312 that was in the parts truck.

 

It sounds like alot of people who have rebuilt a 1956 292 dump the distributor for a newer one don't they? On that note is the carb that is currently on it (carter wcfb) a good one to stick with?

 

The carburetor is probably just fine, but - it isn't designed to be used with the LoadoMatic distributor. The only suitable carburetor for the LoadoMatic is the "teapot", it uses a source of Venturi vacuum and manifold vacuum in combination to provide the right signal.

Assuming that's what you have - you'd have to change the oil pump, oil pump rod, and find a post 1956 dual advance type distributor. These are getting a bit scarce too, good rebuildable cores anyway. This is getting off into the weeds, definitely find out what it is that you have. A LoadoMatic distributor will usually have two "pancakes" externally, and there are springs visible on the advance plate when the distributor cap is removed.

 

This is what I got for a distributor

 

Yeah, that's a Load-o-Matic, a vacuum only type advance mechanism. It will not work correctly with anything except the factory carburetor. A lot of people claimed they didn't work very well even with the factory carburetor.

 

The 1954 model year is significantly different than the later years. While it looks very similar, only a handful of parts are directly interchangeable with those from later years. Some things, like the timing cover, water pump, and fuel pump or distributor, oil pump shaft and oil pump are interchangeable, but only if you change all three at once. You do have to put the original distributor gear onto the newer distributor so even that's not so straight forward.

'55 and up, including the 239 that year would be more or less "conventional" Y-Block.

If the engine in the '54 is, in fact the '54 engine it came with, keep it for the next owner. These parts are very hard to find because they are 1 year only. By now, it could have one of the bigger brothers installed.

 

Good to know, you are referring to the 239 in my 54 "good" truck right? I don't plan on doing anything with that engine but keep it running until the 292 that I have in the 54 parts truck is rebuilt and I can swap them.

 

Yes, the 239 in the good truck. Keep the 239 around even after the swap. Very difficult to find those parts and if a potential buyer wants a "correct" truck, having the 239 makes the truck more valuable. The 239 itself is not very valuable but if someone wants a correct '54, it makes all the difference because of how hard they are to find.
