I need to know if the Dodge/Plymouth(small block) and Chrysler/Desoto(big block) flatheads use the same diameter rod journals. I'm bidding on some 251 Dodge bearings and need to know if they'll fit in my 230 Plymouth. Thanks in advance.
jeff, contact the guys at vintagepowerwagons.com. i sure don't know the answer, but i'm certain they do. the number should be on the website. if it has anything to do with these old mopar flatheads, those guys are a great place to start.
