1957 Ford Thunderbird 312 Y Block Engine

- Hello,
This is a 1957 Ford Thunderbird 312 engine I built for D&D Auto Body. The engine is out of a one owner car. From what I understand the Thunderbird was purchased for the owners wife. I'm not sure how the car was stored, but the engine was in bad shape. The crankshaft had the typical cracks in it as most 312 will have. All pistons had been damaged from weather. All valves had heavy pitting and/or cracks. The rocker shafts had deep scoring. And all oil passage ways had been plugged with old sludge. Now the engine runs great and will be powering the 1957 Thunderbird once again.

nice sound y Blocks forever
Very nice Y block!
Built a 292 up in late 60s. Ran great with balanced lower end and Isky valve train mild cam headers. Seem to recall seeing ads in Car Craft or another Hot rod mag about aftermarket Mickey Thompson hemi heads for these. They were about 500$ at the time. Hell of a lot of money at the time. Does anyone else remember them? I am sure they breathed a lot better than the stock heads which were rather mediocre compared to the Chev 283.
The Y block always had a very unique sound , one of the coolest sounds ever .
I think so too. Smooth fast idle. Great little motors.
My father had a 1956 Mercury Monarch Canadian-made car with this engine in it with a 4 barrel Holley and he did some mods to it and I remember him doing 1/4 mile races against the local cars of the same vintage and he was always at or near the fastest. This car was close to 4,500 lbs and was doing somewhere in the 90's miles per hour.
Sounds a bit like a flathead. Nice smooth rumble.
They have the same firing order.
Good looking engine!
Thank you!
Wow is all that comes to mind
Nice 7.3 I got one just like it
Nice
Built one in 2004. Timing chain points threw me off. 3 o'clock.
It's nice to see a video on something other than a small block Chevy! Are engine rebuild parts pretty hard to find for these old Y blocks?
Thank you. If you're trying to go for a 100% restoration, then yes. If you're just looking to rebuild and not worried about OE parts, then I'd say not really. It just takes awhile to get the parts. I've worked on two of these engines and I found it easier to get the external parts for the two barrel truck Y block.
Nice video, I’ve got a 57 fairlane 500 with the 312. Quick question, what is that lever on the exhaust flange for? Right at the end of the video on the passenger side
Heat riser valve to force hot exhaust air past choke spring to open choke .
The Ford Y block - Heavy, long-stroke, stacked-port, low RPM, rocker-squeaking, main-leaking POS.

Hope you added auxillary oiling lines to rockers.
I replaced the stock rocker shafts, they were worn and plugged with oil buildup. I also did the modification where you block off the rocker shaft bleed off tubes, so oil is forced to lubricate the rockers. Doing this also helps keep the oil pressure up and that helps the main, rod, and camshaft bearings. I also made all oil passage ways line up by removing edges and smoothing out casting. I have videos of all of that, I just never uploaded.
@@SpecialedSpellcaster Nice job. Still hard to believe professional engineers did not forsee these oiling issues from the start!
@@SpecialedSpellcaster 312 Sounds Sweet! I’d love to see the video of your modifications. I’m about to start building my 312 w/ ‘58 Big G heads and ‘58 exhaust manifolds. Running a ecz-9425B manifold. Going to order an Oregon cam & lifters too.
@@spaceghost8995 the rocker arm oiling issue wasn't as common as people made it out to be . In most cases it was due to poor maintenance habits .
Got a good std size 312 motor. For sale was dad just sitting in yard give offer had two fours on it could be in garage
What part of the country are you in? I could use your services.
Hello, thank you for watching, I'm in Northern California. I'll be more than happy to help anyway I can. Where are you located?
@@SpecialedSpellcaster Thanks for the reply. Unfortunately, I'm on the opposite coast.
wear did you get the side engine brackets
Hello, as far as I know they're the original side mounts. They were on the engine when it was removed from the frame of the 1957 Thunderbird.
@@SpecialedSpellcaster thanks
