I just finished tearing down my motor (it was the topic of a thread in classifieds "292 in oregon"or some such B.S." a few months ago. Anyway, there were a few bets on what it would really turn out to be, 239, 272 etc. So it's a '55 272, with 5257-113 heads and a weird two barrel tea pot/governed carb, with a 4 speed of some sort...Anyway, to the point. Upon removal, all of the mains have wear only near the clamping point where the two halfs meet. It seems odd to me, how about you?...
