Any Lincoln Y-block Gurus here?

Need some help to i.d. an engine . its a Lincoln or truck Y-block but I cant find any references for the numbers on it.
Cast in block beside dizzy and again above starter on side of block is 5750281 .

Cast in side of heads is 5750117

cast on passenger side of block ahead of engine mount boss is 80y:2

cast on heads under the rocker gear is 80f on one head and 80h on the other.

Stamped into a machined face on the drivers side of block below head is 3-81Em

it has rams horn style manifolds with ECS9430A cast on them .

So any clever blokes out there who can help ? :cool:

I don't know. Your numbers don't seem to jive with any that should be there. Here are two sites, which you have already probably looked at:

Are you sure this is a Y block? One thing that leads me to think it is would be the rams horn manifolds, those were used on some of these engines.

Very puzzling.:confused:

hey thanks for the links gentlemen, yes I had looked there . This thing is definately from the " big Y" family based on the lincoln , I have my suspicions that it is a 332 truck engine but would like to be able to confim that .

any leads/info really appreciated .

I think its a 317 used in Lincoln's and trucks the call it a y block but i don't think any of the parts interchange with 239 272 292 or 312 if you look at it I am sure you will find it does not have the stacked intake ports like the ford y block if you go on e bay type in y block these show up from time to time as far as I can tell there is no speed equipt. made for these sooo if ya got a boat all ya need is a chain......ted:LOL::LOL:
