Thanks for watching my back Joe, but the FAQ isn't where I got that information, and I doubt I believe everything I read anywhere. That being said, my reply was correct.

It's actually 68-76. The casting number changed in 1977 when the went to the windowed mains and ½" head bolts.

Every single Olds 350 block from 1968-1976 used that casting number. This is yet another well documented error in the Olds FAQ.
