I just found out what I thought was a 292 turned out to be a block cast with "EBY". All this time, I have been moving forward as if I had a 292. John Mummert Ram Horn exhaust fit, intake manifold ECZ 9425-B swapped out ok (500 Edelbrock Thunder Series Carb), GM one wire alterntor, new oil pump, and YBlock Moon Valve Covers all seem to fit fine.  Somewhere along the line I thought I had a 292 which appears to be a 1954 Mercury 256 V-8. What exactly do I have here and is it worth keeping or should I be looking for a 292 to swap it out?

Your 256 can be stroked to 272 just by swapping the crankshaft. With a 292 crank it might be possible to bore it out to a full 292 engine. But you might consider selling your 256. I suspect that you might find a buyer. If you lived in my area, I would trade you a 312 block for your 256.



If your goal is power, you are better off starting with a good 292 block and going from there. I recommend finding a B9AE or similar 292 block. If your goal is just building a cool cruiser, your 256 qualifies. Get some Mercury valve covers, a ECZ-A intake and a Carter WCFB and you're good to go.

Paul,

I am from Whitefish, MT. Thanks for the offer on swapping a 312 for my 256. I have another 56 Ford F-100 that has a 351 Windsor 425 Horse so  needing  another power rod is not my goal. I came across another 56 but it was way too nice to use for a parts truck so I have ended up sitting the first project aside and making the 2nd find a driver. I am fine with the 256, but dissappointed I made so many changes before I realized it was not a 292. It was running and sounds really good. To date, I have taken it apart and swapped the intake with a ECZ 9425B. I have bought an Edelbrock 500 Thunder Series carb and an MSD Electronic Distributer. I have changed out the fuel pump, clutch and throwout bearing.  I have removed the original exhaust manifolds and am adding the ramhorn exhaust manifolds.

My biggest concern is whether or not  any of these changes will be an issue when I go to fire it back up. I just wanted make these modifications and get it running again and drive it until I needed to rebuild the engine. That would allow me to return to my other truck and get it running. While I am doing that, I would still have this project as a driver and be working on making improvements.

Do you see anything I have changed that would be determential to the 256? If not, I will finish it up and maybe keep my eye out for a 292. If and when I get around to rebuilding the 256, I will be looking for a good rebuildable 292. Thanks again for your help.

Where is Meridian?

Just checked the distributer removed from the 256 and it has 14 teeth on the drive  (same as MSD) and a hex intermediate drive to the oil pump. Don't know if thats original equipment in this 256, but at least appears to be compatible for the distribuer swap. I'm a little nervouse about what I may have gotten myself into by thinking I had a 292 opposed to the 256. Hoping the intake I swapped out will be ok

Darrell:

If the engine has the '54 heads, it is possible that the intake gaskets can't make up the big difference in port sizes.  If you don't have a vacuum leak, it will probably run OK, even though the mahifold ports are larger than the head ports.

John,

I just checked and the heads are ECG-D (55 Ford). I checked the gaskets against the intake and the head by placing on the bolt holes (intake) and studs (heads). Its a perfect fit. I am hoping this means I will not have a vacum leak due to mismatched head/intake allignment. This may let me fire up the 256 with swapped out intake, and Edelbrock 500 and MSD Distributer (292 Yblock). The distributer seems to fit fine and both had the hex intermediate drive and 14 teeth on the gears. I had already changed the starter, fuel pump, and water pump thinking I had a 292 and they all worked fine when I started it up.

I then proceeded with removing a multiple wire ford alternator, intake manifold, and exhaust manifolds to swap out with new intake/carb,  distributer, ram horns, and GM 1 wire alternator. In the middle of this, I discovered I actually had a 256 instead of a 292.

Anything you see here that puts up a red flag? I will be looking for a good 292 rebuildable block and heads so if this engine gives it up, I can swap over to the 292 and have some fun with it.

On another note, what is your opinion on using stainless bolts to hold the manifolds (intake and exhaust). I understand anti sieze is necessary, but wonder if the heat will defeat the purpose of the anti sieze and justify using grade 3 or 5 bolts instead. I have this little issue with using stainless steel bolts, grinding off the heads to a flat surface, rounding the edges on the top, then polish and using to install satin black components. Just not sure areas with high heat this should be considered. Thanks again for your advise.

Hopefully, all this will help someone else.

Darrell, From the sounds of it, you should be ok. I think that all the stuff you got should work on a 55 y-block, especially if it was a passenger car y-block.



I actually live on the town line between Boise and Meridian; my property line is the town line, but technically I live in Meridian not Boise.



I think the best block for building a 292 is the B9AE block, but be aware that some B9AE blocks are 312 blocks. I just bought a 312 B9AE engine block.



Let me know if you need any odd parts. I might be able to help.

Paul,

I have located a 292 in a 1964 ford pickup. The owner says the truck has sat idle for 25 years because of a transmission leak. He is going to get me the casting numbers off the block and the VIN number. If I can verify its a 292, what do I look for to make sure its not a 312? I offered him $200. This engine is complete to include all tin.

That block might be a C2AE block. John Mummert has a web page that lists a lot of technical information. www.ford-y-block.com



That engine assembly might have the good C2TE rods and a good crank. The main webs of the C2AE block will be thicker than early y-blocks. I had a C2AE block for a short while but found that the #4 cylinder had some core shift, visible through the frost plug behind the starter, so I returned it. Many builders, including Ted Eaton, look for C2 blocks to do their high performance builds.



The C1TE heads that are probably on the block are ok, especially if you zero deck the pistons, but they're not used for performance builds. If I ever rebuild a pair of C1TE heads that I have, I'll swap some 1.72" intake valves into the head.



I think it has a good distributor, too. Probably a Holley 4 bolt, 2 barrel carb.

Best regards,

thanks Paul, will check out Johns site for more info. What is core shift.
