I'm still getting acquainted with my new truck.

"Ford-yblock" shows an ECZ block for '56 but ECZ isn't listed in my shop manual. According to the website, this block ID number for this truck should have an A but instead has a C. Is this a late production '56 or is this engine a '57?

Also, does anyone have stock engine compartment photos available?

Correct color for this block?

Thanks, Doug

 

According to Mummert's data the ECZ-C is a 1957.

 

Doug,

Here is a thread with lots of information about the engine colors. Engine Colors

There is also some informaiton at Earl's World through the link in my signature block below.

I have five or six stock 1956 engine bay photos from Pigeon Forge 2003, but right now I'm having trouble with my FTE Club web site and can't log in to upload them. If you'd like, I can e-mail them to you provided you send me an e-mail first through your FTE membership. Posting e-mail addresses is a no-no due to security issues.

 

Check my gallery for engine color pics. I think one of Georges pics is my truck at Pigeon Forge.

All 1956 factory brochures show YELLOW engines. Ithink my "OTHER" part of my gallery shows a factory color pic from a brochure.

Most of the ECZ-C blocks were 312's but about there were a few 292's

yours is a 1957 production engine and is probably a CAR engine.

George I went to the enginecolors"link and the pic you have posted didnt come up. Is this a pic of my engine?

Kevin,

It could be. Right now I'm locked out of all the stuff on my Club FTE web site and I can't upload or post anything. I probably deleted or renamed the actual image file I used in the post on the old thread. The server can't find the JPEG file on my Club FTE web site and therefore can't show it. I'm working on a fix for the computer problem, but am on babysitting duty with 2 year old grandson. He likes to help with the computer buttons and mouse, so things take a lot longer. I wouldn't have it any other way, though.

 

it should be a 57 car block 312.i have one from a 57 fairlane and its a 292.when ford was short of blocks they just used whatever was handy.

 

Thansk everyone...

312...are you saying that the engine may be original even though it isn't "correct"? By the way, it's red.

George...Thanks for pointing me to that thread. I'm very interested in those pictures.

Here's some info from ford-y-block...

HOW TO IDENTIFY A 312

IT IS NEARLY IMPOSSIBLE TO ABSOLUTELY IDENTIFY A 312 EXTERNALLY!

312's were installed in 1956 Mercurys and some 1956 Thunderbirds. Many 1957 Thunderbirds had 312's and all 1957 Mercurys had 312's unless equipped with the 368 Turnpike Cruiser engine. Some 1957 Fords had the 312, typically station wagons, Fairlane 500's ect. All 1956 and '57 312's had 4 barrel carbs. From 1958 to 1960 312's were only installed in Mercurys. No 312's were installed in trucks at the factory!!!!!

BLOCK CASTING NUMBER:

312's can have the following block casting numbers ECZ-6015A, ECZ-6015C,EDB-6015E, B9AE-6015F. Of these ECZ-6015A and ECZ-6015C are by far the most common 312's and are likely to be a 312. Some 312 replacement blocks were C2AE-6015C. Any of these numbers can also be a 292. The following blocks have never been seen as a 312: EBU, EBY, EBV, ECG, ECK.

CRANKSHAFT:

312 crankshafts typically have an identifying mark on the crankshaft flange. This cannot be seen if the engine is installed in the vehicle with an automatic transmission. On a manual transmission vehicle the mark might be seen between the block and flywheel. If the engine is out of the vehicle and the bellhousing is removed the mark can be seen. Many 312 cranks are stamped ECZ, but not all are.

Not all 312 cranks have this aspirin size raised dot!

MAIN CAPS:

312 main caps are always marked ECZ , all other Y-Block main cap are marked EBU. This is the only positive way to identify a 312 block.

 

The ECZ-C is a 312 block.

I've heard that Ford might have put 312's in some trucks, expecially in the western market.

I have doubts about whether a C2AE can be safely bored to 312 size. The C2AE block that I had was cast with thinner cylinder walls, and the cylinder adjacent to the oil filter boss was tilted. Boring that block to 312 bore would have been a problem.

 

there is no difference between a 292 and 312.thats why you find them with each others casting number.a 312 is just a bored out 292 with mains cut larger for the 312 crank.ford made different casting numbers for them but when they ran short of one they just grabbed whatever was handy.hense the mix ups.

 

OK, I've asked this before, but now that we have a new poster, maybe he will know. My Y-block is ECZ 6015B. Yes "B"! So what is it?

 

John,

I'm afraid you're probably going to get the same answer. As Carl and others have mentioned, there are some pretty well-documented cases where factory and replacement cranks, blocks, and heads don't follow the documentation that's out there. From stuff I've read here, John Mummert's Y-block site, on FordBarn, and other places, the only way to be sure you have a 312 is to look at the main bearing caps for the ECZ stamping. I know that's not a very complete answer, but there it is.

 

Thanks George!

 

1. 312's were also an option in 56 Fords, especially wagons and Crown Vics along with some cop cars.

2. When Y production ended in 64 Ford used up many remaining replacement 312 blocks and put them in trucks WITHOUT VIN documentation. Also as Paul mentioned 312's were factory truck installed for use in western mountain states, primarilly in fleet purchases.

4. The B9AE that came in the rotted out 62 F250 that I bought for $100 is a 312. Since it had a 4bbl I took a gamble and was pleased to see ECZ caps.

5. I now have 2 312 cranks with no ****, these are factory replacements.

6. Not everything in Mummerts list is correct and there are some omissions.

7. I dont hold dash letters such as -C as gospel since this is Fords we are discussing. They may give you a warm and fuzzy feeling but until you drop the pan it is always a gamble.
