I use the 4094m bearings on my 440 source crank and while they are a little bit narrower than the clevites , I still had to chamfer them for clearance.



I am running the 4094M's on a Molnar crank with no issues. I am also using the King XP series of BBC rod bearings and have zero clearance issues there as well. I guess Molnar cranks don't need the extra bearing-width clearance on the journals that the 440 Source cranks do. Interesting.
