found and engine

[karl head]

Hi everyone I have found an engine for my truck. I have a question regarding the serial number M-83290, I am wondering if this is a marine engine and if there are any differences between them and a standard truck/car engine

I believe this was discussed before and the M series started in 57/58 for all flathead auto installations regardless of brand. Should be a 230 if its a 23.5 inch block.

Thanks for the incite, I had tried looking it up and didn't find any info the engine is a 25 inch long block

Karl, all Canadian built Mopar flathead 6s were 25 inch blocks. Now this engine ID number could be the same years Greg mentioned, just the Canuck version.

I do know there are some 23.5 inch blocks in Canada, most likely imported from the USA at some point, someone I know has one of these.

Too bad you weren't closer, there isa 265 industrial, close by, sittin on a welder....

Karl, maybe Bill Watson will chime in, or you could send him a PM, He is probably the Man with the absolute most knowledge on Mopar Production History and Facts. Maybe you got yourself a nice 251 or 265 there, can this engine be used without rebuilding?

I am hoping so but wont know for sure until its out and home I really hope its a bigger engine its out of a 48 two tonne. but its not stuck and I tested it for leaks so fingers are crossed. I may freshen it up with rings and bearings before installing it. the owner of the yard say he used it around the yard for a while years ago and drove it and parked it where it now sits .

On the subject of Canadian vs American engines I have a real oddball: a 225 cu in industrial engine!

It uses the 25" long, DeSoto/Chrysler block with 3 7/16" bore. But with a 4 1/16 stroke crankshaft usually seen in Canadian Plymouth, 218 cu in, 3 3/8" bore engines with the same block.

Now get this, the ID plate on the side identifies it as an industrial engine built in Chrysler's industrial engine plant in Michigan! I forget the name of the town but it isn't Detroit.

So, it seems they made many different versions of industrial engines. Not surprising I guess, as they sold so many of them and most of the changes were easy and cheap to produce.
