yes and no
the last couple years of 6.2, when they changed to a one piece rear seal, are the same. the early years are a 2 piece seal and are different

I thought the stroke on the 6.5 was .020 longer? The 6.2 have 2 piece rear main seals except for some of the last ones around 1992. The 6.5 cranks use 1 pc rear main seals.

Same stroke, 6.5 has larger bore, ie: weaker block. Leo
