I have a 1956 F250 that has a Y block Lincoln engine installed. I'm trying to find out exactly which one it is and have uncovered 2 sets of numbers:

On the drivers side of the block a couple of numbers 64J:1

On the passenger sideI got ECU601(7?) 5A. Hard to make out the 1 or 7 and I think the last one is A.

Any help on this appreciated.

 

see attached Y-block site.

Nice, 368 cubes if I read Rocketman55's link correctly. 285 hp for the 56, 300 for the 57. You need to bring that engine to life.

 

Wow, Hot Rod Lincoln!

 

YES! Commander Cody and His Lost Planet Airmen!

 

I would love to do that but I don't think it's in the cards. I think I'm going to be selling this jewel.
Have to talk to the wife...

 

Thanks for that info. I had seen the lincoln page before but I was confused. The one you sent seems to point to the 368 which would be really sweet.
