I am working on a 251 to replace the stuck 230 in my 52 dodge pickup. The engine I found is a rebuilt 251 that was in an M-37. I know this is a 25 inch motor instead of the smaller 23 currently installed in the 52. When I got the 251, it didn't come with a starter so I put the 230 starter on it. This is before I realized the 251 could have a different flywheel tooth count. Anyway putting the 230 starter on was no problem and it worked fine - didn't bind up and sounded ok. So is this normal? The M37 that I got this motor out of was an ex brush fire truck from central Oregon. The front mount was welded to the frame instead of bolted. I am betting the M had a 230 originally and it was replaced with the 251 at a later date. The serial number on the block is from a 48 to 49 truck. So I now have a few questions. First - could the 230 flywheel fit on this motor (explaining why the starter didn't get bound up)? The 52 has a three speed fluid drive. Will I be able to bolt the fluid drive to the 251? I'm pretty excited about getting this motor installed it the 52. I fired it off briefly and it sounds really strong. Can't wait to get it cleaned up and ready to go. I have it on a run in stand so it will be easy to work on and get running before being installed. Any help you can provide would be great. Thanks for letting come here and ask questions. The 52 is going to be treated a dropped front axle, new brakes, and a higher geared rear axle. I have not decided what I want to do with the body. For now I just want to get it on the road with a good reliable engine and updated suspension.
