Ah well, it's a 235, casting number 3701481. So that makes it a full pressure block, but the head is a "low pressure" head, which I guess is ok. But it's not the elusive 261. So Tim is correct about the captain's bars on the '53 Powerglide 235s. Not sure if I should make the hour and a half journey or just get the '54 one that's a mile or so away. For less than half the price I'm going to go look at that one first.
Thanks for all the valuable info.
