Clevite list main bearings ....MS1051P for 71-73 360 sb
MS1266P for 74-78 360 sb (full circle oil groove)
My block is a 73. The specs for both of these appear exactly the same on their site. I ordered the 1051P, but was sent the MS 1266P. Does anyone know if these mains are definitely interchangeable, and what ...if any, differences are there in the year castings /crankshafts??
Thanks
Bruce
