Looks to me like it has a passenger car pan. hard to tell from those pics.

Also has pass. water inlet.

Still might be a decent buy if it runs. the valve covers are valuable as is the air cleaner, A 292 is just fine, 312 is highly overated.

Charlie's right almost anything can be bolted on - the valve covers and air cleaner are easy changes. Four blade fan is odd for a bird but some got changed due to breakage.

If there is a LH exhaust manifold specific to the bird - casting prefix ECJ - and a tach drive distributor??? One inch spacer between the waterpump and front cover.......

It's not a T-bird motor.

Weren't the T-bird specials that were available in cars 312s if they had the T-bird valve covers? The problem with that is how do you know if the valve covers are original to the motor.

Here are pics of the engine.Don't know if you can tell if it's a 312 or not, maybe someone with a keener eye could spot something. Thanks for the advice anyway. Randy

That's one rare '56 F-100

At a show this summer there was a '56 F-100 with a big sign in front of it telling everything that had been done.  Included on the sign was "Engine-Original 312".

Mike, located in the Siskiyou mountains, Southern, OR 292 powered 1946 Ford 1/2 ton, '62 Mercury Meteor, '55 Country Squire (parting out), '64 Falcon, '54 Ford 600 tractor.

The casting number on the block doesn't help identify a 312. Any # used as a 312 was also used as a 292. There are some numbers that never were 312's, EBU EBV ECK ECG B5A EDB(Dearborn). I have never seen a C1AE 312 but won't swear they don't exist.

ECZ-A or B or C , EDB-E(Cleveland)  B9AE C2AE can all be 292 or 312

A real 57 312 will have the ECZ9425B intake

If you can find the right buyer for real T-Bird parts a 57 engine is worth a lot, easily 1000.00 but you have to take the time to sell them. Dizzy-400    damper-400  oilpan-200  LH exhaust manifold-175     ECZ9425B intake-125. Prices will vary but you could sell off enough to have what you want for free.

Those #s could also be on a 292, you would need to drop the pan and look for ECZ on the main caps. Also as mentioned earlier look for the "dot" on the flange.

I was researching 312's from y-block.com and block casting numbers are ECZ-6015-A,B,C,or E.

Are these numbers specific for 312's?

If it's a t-bird motor... a couple of quick things to look for; 1 inch thick spacer behind the water pump, generator mounts in front of block,not along side,  crank damper and pulley (s) are distinctly different than regular y-blocks. As for it being a 312...really hard to tell without taking the pan off or looking for the "dot" on the rear of the crank, which is hard to spot with the trans on.  Don't pay  premium $$$$$'s for it without being sure. If you don't need T-Bird specific parts, a 1000 $ is too high unless it runs fairly well.   Just my opinion ,but it seems there are more 312's for sale than were ever built. Good luck    Barry
