When I say 302 and LT-1 I am specifically referring to the 010 casting of both and 010 castings produced in Michigan.
FORD had the Windsor then they had the Cleveland These were technically different block designs and as we will soon see GM did the same thing with the 010 changing the design at least 3 times while keeping the same casting number.
I asked about this. I was told that these subtle changes were accomplished to at first to transition the engine from a high compression centric design then later again to adapt the block to better meet durability and emissions as GM moved to a corporiate engine usage format. These later 010's are the two bolt variants and are easily recognizable by the small pad where the usage designation was stamped which was shared by the 305 also.
