Who can tell me if there is any difference between a Ford or Mercury 292 c.i. engine. Maybe identical except for the I.D. number? And will the 292 bolt right in as a replacement for my '54 Mercury 256 c.i. motor? Reason for asking: my 256 motor developed a water leak somewhere in the back close...

I've got a 54 (Merc) 256 c.i. that runs cool (160 degrees) above 40 MPH but 190-200 traveling 20 MPH or less. Here is what I've done in more or less chronological order. 1. Had the radiator re-cored with 4-row core. 2. Added 6-blade fan. 3. Rebuilt the engine. 4. tried 180 & 160 thermostats...

I have converted my '54 Mercury from manual to power steering (necessitating a change to floor shift) and am having trouble getting the lights and turn signals working. All of the wires that run through the steering column have faded so the color codes in my wiring diagram are no help. I put...

I'm in the process of converting my 54 Mercury conv. to power steering but there is no way to get the manual column shift to work. This is due to the power steering gearbox being longer than the manual box. Also, my steering conversion kit is made for 52-56 Fords. Fords have an external shift...

I am in the process of a project to convert my manual steering system to a modern style (No Slave Cylinder) power steering. First of all, I need to say that it's a Mercury (54) not a Ford and therein lies my problem. The problem is with the manual column shift levers. I'm using what's known as a...

I have found a company that makes a power steering gearbox to convert Y-Block Fords & Mercs from manual steering to power steering without using the problematic, leaky slave cylinder like the factory set-up. It's manufactured by a company named Borgeson and sold through Summit Racing. It appears...

Does anyone know if a '56 or later 12 volt starter will fit a '54 mercury that has been converted to 12V? Thanks, Scott

I just installed a replacement ignition switch and a headlight switch. My starter was trying to engage after I turned the key off and my dash lights weren't working; figured I might as well replace the headlight switch while I was working on the key switch. Anyway, when I hooked the battery...

Does anyone know if there is a procedure for replacing the rear main seal in the 239/256 y-blocks without taking the engine out of the car? My shop manual only explains it with the engine out. Some of other my other brand shop manuals explain it with the engine in the car but not my '54 Mercury...

I can't get my clutch to disengage properly. I've installed my rebuilt engine. When I removed the transmission, then the engine, I found this small piece of metal on the floor under the car. It is about 1/8" thick, 1" wide, and about 1 & 3/8" tall. It has rounded ears on the top and bottom and...

I took my 256 Merc engine out for rebuild and thought I put the motor mounts back on the same way they were before but the engine won't go back in and line up. I thought that the open end of the "C" shape of the motor mounts was supposed to face the rear, towards the firewall. Can anyone tell me...

I took my 256 Merc motor out to rebuild and thought I put the motor mounts back on the same way they were before but it won't line up correctly. I have them mounted with the open part of the "C" shape to the rear towards the firewall. Can anyone tell me if this is correct? Thanks, Scott
