Jordan, the motor in your carrier is the proper style for it. That's the only kind they put in them.
If you go to overhaul a 221 ci flattie, the 37 and newer used replaceable main bearings where the earlier ones had poured babbit mains. If the motors weren't rebuilt at one time, they have the dual faced rod bearings too which makes the motor more expensive to rebuild. As for cracked blocks, the cracks that form radiating from the head bolt holes don't matter. It's the ones in the valve seat area that turn the motor into a boat anchor.

Jordan: I have had a bit of luck with Flatheads this summer. I bought one to use as a quick install on my carrier, and picked up a second truck that shows the promise of running. I gotta quit hanging out at auctions. Both are 49s unfortunately, so the water outlets are in the front of the heads and not in the middle. Shame you are not out this way or I could make you a smokin deal on the spare. The 49 Fords can be converted back to the hard access position for the distributers, they already have the right style water pumps, but unfortunately there is no way of fixing the water outlet positions.

I was thinking that all the 221s were 21 stud engines but they weren't. I guess you learn something new every day. They made 24 stud 221s from 1939 to the end of the war (85 hp) and these are the ones used in the carriers. They look the same as the 100 hp ones in the CMPs. Around here the 100 hp flatties aren't too hard to find although the 1949 and up engines are easier to come by. I have several of the newer ones including some 255 Mercs. It seems that by the early sixties when a farmer put a rebuild in his truck it was usually a 255 for the horsepower gain. I also have several of the CMP style engines but then I also have several CMPs that don't presently have engines in them.
