Remaned engine decoding

[furiousgeorge]

I just picked up what I was told was a 251 from a early '50's truck. It starts and runs good, but uses oil. I just wanted to decode it and make sure I know what I've got. It's what I assume to be a Canadian engine, and has a rebuilders tag on it. I've checked out the t137 site, but nothing matches my number. The stamped number on the top left of the block is 22872, no letters. On the rebuild tag, it says R63 22872. Can anyone help with this?

Is this the motor from Radisson?

Did he have any other flathead parts?

Nope, tried that guy a few times, but never got an answer. Found this one in Nokomis.

If you have plans to build it you can remove the head and measure the bore and stroke, that will also give you your displacement. My 251 numbers meant nothing either when I tried, it was a rebuilt engine from Winnipeg that was out of a combine.

[furiousgeorge]

Yeah, I was planning on freshening it up, so I'll just have to messure. I was hoping to figure it out before I tore it apart so I had the right parts on hand to rebuild it. Oh well. Thanks for the info!

How do you know what rebuild parts are required with out first measuring what you have? And if machine work is required I always let the machine shop recommend and order the required parts after the machine work is completed. I have never had a machine shop over charge me on the cost of the required parts and if they order the parts they will stand behind there work.

I was thinking gaskets and things that I'd need to replace regardless. If what the previous owner said is true, it's got good compression, but uses oil. He figured the oil rings were stuck.

[NiftyFifty]

Honestly, it's more likely more serious then that, and be prepared that if it was an industrial engine, it will have different Pistons in it, and tougher to find rings. You can go ahead and order the gasket set, it's all the same for the 25" block, just be sure to order the set for internal bypass or external based on your water pump and head. I can get you a Fel Pro number if you need.

Northern Auto Parts is a good cheap source for quality engine parts, but if it was me...I would bore it to a good clean surface and get the crank plasti gauged, or you may end up with low oil pressure

Could you please check what carburetor model number is on the forward fin of the carb itself ?

 

Thanks,

Sorry, it didn't come with a carb, or starter, generator or fuel pump. That's how it got down into my range of affordability!

[furiousgeorge]

Alright, life finally calmed down enough to get back into this! I measured it out (bore and stroke) and it looks like it is indeed a 251! I also just picked up another engine that the owner figured was a 251 (mainly for all the bits mine is missing). It turns over, and is complete minus the air cleaner (with the car bell housing and standard transmission). The number on the block is P23, which unless Canadian numbers are different, is a '52 Plymouth 218 according to the t137 website. Not as awesome, but I was never planning on running it anyways. Could someone post a link to where I could decode the carburetor if possible? It's a Ball & Ball, the numbers stamped on it are B1 D6L2 and 6-595. I'd like to know whether I got lucky and a larger carb was put on at some time that would work well with the 251.

Thanks!
