Flatty52 Posted February 10, 2012 Report Share Posted February 10, 2012 Hello all! Newbie here from Alberta. I bought a 52 Cranbrook with tired 218 long block. I have the chance to buy a 251 tug engine completely rebuilt and am wondering about swapping it for the original and what kinds of issues I should be looking for. I'll be running a George Asche OD tranny if this matters at all. Any info/advice would be muchly appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
41/53dodges Posted February 16, 2012 Report Share Posted February 16, 2012 I don't know a whole lot about the 25's,but I have heard they are interchangeable. you would get more answers by checking the search function, then post somewhere if you dont find the answer.

oldmopar Posted February 16, 2012 Report Share Posted February 16, 2012 Some of the industrial engines have a plate on the right side providing the engine model with that information you could find more information about the engine. I think some of industrial engines ran with less hp and lower rpms then the auto engines. Quote Link to comment Share on other sites More sharing options...
greg g Posted February 17, 2012 Report Share Posted February 17, 2012 except for some of the accessories, and linkages, should be a bolt in in a Canadian car. And even if the 251 is detuned a bit for the application, it will still make more HP thant he 218. I had though that engines made for stationary or some other industrial applications, might have different cams as they were going to be operated in a fairly constant (and in most cases lower) RPM ranges than automotive applications. But this dosan't seem to be the case with Chryco engines. Most were never meant to be run at high rpm regardless of operation, so no different cams were used, except in counter rotating marine applications. You may find some differences in the crank shaft flange thickness and or flywheel offsets so you need to devine which pieces parts will complete the swap, but the engine should just go in.

Rusty O'Toole Posted February 19, 2012 Report Share Posted February 19, 2012 You may need to use the 218 oil pan for steering clearance. It will interchange with the 251 if the 218 is a Canadian engine. To make sure, measure the length of the engine at the cylinder head. Canadian 25" US model 23 1/4".
