I went and looked at a junkyard Mercury Y Block today that had been sitting out in a pickup bed for a long time. Intake was gone as well as some spark plugs and water in the block. Rebuilt tag indicated mains were ground .010 and rods .020 with .040 overbore. Pretty sure the block is junk, but had a good valley and oil pan. The heads were COAE which makes me think it is a 1960, but the crank flange confused me. There was a very small raised dot on this crank flange and nothing like the eraser size raised dot on the 312 Ford cranks. So is there a difference between the Mercury and Ford 312 cranks with respect to the dot on the crank flange? If it's a 312 I'll go back and get it. He only wants $50.00 for it. Sorry, I don't have a photo to share.

Check this link on the Mummert site for crankshaft identification. It shows the small dot cranks.

Its prob not a 312.

no difference

For $50, if you have room, get it, no matter what it is.  The block might be fine but even if it is not, the remaining parts are easily worth $50.00.  They aren't going to get easier to find.  Don't let them go to scrap if you can.

I agree with Charlie - buy it. The rods and crank may as least be salvageable. It sure sounds like a '60 Mercury? If this is the case, it would be a 312. If I can remember, the 60 Mercury valve covers were kind of a light green as opposed to a darker green used in 57?

Ron, I’m in the market for a valley pan to modify. I can take it with the oil fill tube cut off, so shipping is cheap. That should get most of your money back for the whole deal.

If you get it post a couple pics. Nothing more fun than scoring and exploring a salvaged Y-block. Good luck.................

Okay guys I got the motor and fo an extra $10.00 the tranny too, but I'm not sure if the tranny actually belongs to this Y Block. I have been searching the internet to try and I.D. the tranny, but can't seem to nail it down. The bell housing has the casting PAR-7975-A but doesn't look like anything I have seen on line. The transmission has no tag that I can find, but has the casting # PAW-7006-A.
I think it is a Merc-o-Matic, but maybe it's a Lincoln tranny. 1960 seems to have been a transition year. Any help would be appreciated.71% of original size (was 712x19) - Click to enlarge71% of original size (was 712x19) - Click to enlarge71% of original size (was 712x19) - Click to enlarge71% of original size (was 712x19) - Click to enlarge71% of original size (was 712x19) - Click to enlarge71% of original size (was 712x19) - Click to enlarge

The motor seems to be a 1960  312 with the EDB block casting. I took a couple of pics of the crank flange but they are a bit fuzzy. It still looks like 1 small raised dot with a single half moon cut out on the flange. Valley pan looks like it has the original PCV valve set-up. Miker, send me a PM so I can get that to you if you want it.

As you suspected    that trans did not come from that engine, the crank has a pilot bearing for a stick shft
