John's 261 was an early design high water pump type- - - -bypass filtration and all. It turns out that one was a replacement block cast in 1959 for a 54/55 early casting design. The main bearings bores were machined for the 55-62 bearings, however, so there was a bit of drama making the early-style main bearings we had ordered fit!
