In reference to sodium filled exhaust valves in the truck heads, I’ve come across an earlier model Y head with sodium filled valves than what’s posted above. This one is 1954 vintage with EBZ-L casting numbers.

Heres a picture of what appears to be a 1 bbl carb on a Y-Block Onan generator. Look as like an adapter on a 57 and later 2 bbl manifold

I have a pair of ECR-D I think with the sodium valves and these heads have the smallest combustion chamber I have ever seen, almost no step from head surface to chamber. Do you know what the combustion chamber size is on your ECR heads Ted?

John (Hoosier). No problem. I was answering John (Mummert) in that the oldest sodium exhaust valves he had seen in Y heads was for the ’59 models. I have had cylinder heads with sodium exhaust valves going back to at least to 1955 for the Y engines just as a matter of general information.

Ted:

I didn't mean to say that '57 heads couldn't have come with sodium valves, I meant to say that they weren't put in G heads, but in industrial casting numbered heads. Incidentally, the sodium version of the 471 heads had B9TE casting numbers.

John. The oldest heads I currently have with the sodium exhaust valves are pairs of ECR-A’s and ECR-C’s. Based on the date codes, they are 1955/1956 vintage.

Those G heads on it would not have had sodium valves from the factory, but that's not to say someone didn't put them in them. If they are sodium filled, they will have 7/16" valve stems instead of the regular 11/32".

Someone sent me a picture of an Onan generator with a Y-Block. It looked like a 1-bbl carb and governor.The mid 50's industrial short blocks didn't appear to have any special parts.
I have used them for car builds.
Heads might have had sodium filled exhaust valves. Not sure what year they were introduced. The oldest heads I've seen with sodium valves were 1959. They were common in -471 and C1TE heads.
If it has ECR heads it is HD truck or industrial. I've never seen a set of these heads in person to see if they had sodium valves.

Could that single barrel carburetor be for propane. If so it may have had former life in a forklift.

Yblock Billy the 53 Jubilee (NAA models) Ford tractors used the same lifters as the yblocks

One other note is the fact that some of the 4 cylinder ford tractor motors from the late 50s and 60's and maybe into up into the 90's with the 4 cylinders share the same lifters as a Y along with same bore and pistons as a 272 I believe, not sure of the rods.
