This past weekend at my Brothers resort, I went on a hike and made quite a discovery. I found an old Mercury, I had seen it before, but never paid attention to it. Its a really old 1? ton Mercury (ford in canada back in the day).

 

Does anyone know anything about old trucks here? Whats its value? I have pictures but I can't find my camera, its packed away from the trip still somewhere.

 

Visual things I can tell you about it:

 

It says M-3 on the chrome on the hood, its that sky blue/green color and it has a flat head v-8 in it.

 

Is it worth anything??? I have heard those flat head motors are worth some coin.

After reading several online sources for more info, it just might be a 1951 Mercury M-3 1-ton truck. Think of the Ford F3, or the F-350 nowadays.

 

The engine is a little bit tricky to identify (for me) without a good visual. My best guess on this is that it's the 239 ci (3.9L) Ford Flathead V8 with the passenger camshaft and a 4-speed. 106hp @3600 rpm and 225 lb-ft @ 1900 rpm. Bore & stroke ratios are 3.1875 x 3.750, compression ratio is 6.80:1, head bolt count is 24, and a Ford-Holley 2 bbl as the carbuerator.

 

Gross vehicle weight is @ 6800lbs with a 122" wheelbase.

 

If you have a pic of the serial plate, that would help me immensly because all the info I've stated is basically guesswork. Also, here is a link for more info on these trucks.

 

If I had money, I'd tell you what I'd do. I'd go downtown and buy a Mercury truck or two... :sigh::lol:

 

And if I'm right about any of this, you would be best off to find out if anyone can claim it (don't tell them that you're interested in it if you are), and if no one claims it...

 

TAKE IT !!!!!!

 

You'll have one of the rarest vehicles on the road aside from the old Studebaker and International pickups of the early 60s, not to mention one HELL of a project vehicle. :thumbs:

 

Hope this helps. :mad:

It appears to be a 1951 from the hood design.

Ahh, ok. Then the bore & stroke would be 3.1875 x 4.000.

 

The Mercury engines of '51 had the 4" stroke crankshaft, and it used the Ford-Holley split float dual downdraft carburetor instead of the the Ford-Holley two barrel carburetor.

 

112hp/225tq.... low by today's standards, but still respectable for vehicles in that timeframe....especially the trucks.

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      By glenn27 · Posted

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      Different requirements for oil filters?

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
