360 main bearings question

I'll second Krazy there but I thought the years were a little different. The old bearing (70-71 castings IIRC) works on everything, newer style works on those with the larger thrust cut. I think they made the change after '71 so some 72 model year year blocks got it.



When I was rebuilding a 74 360, Mancini asked me which bearings I needed as their books listed the bearing change in mid year 74....

Of course I had to have the "questionable" year.... :banghead:


But I have seen older blocks than that with the larger scallop for the thrust bearing that can accept the larger bearing.
