Yeah, Windsor blocks were 2 at a time too....so @my68barracuda do the suffix numbers mean ANYTHING as related to quality? That's the base of my theory. It sounds like a -1 and a -8 (-15) are going to be dimensionally the same? So this last number is meaningless in regards to block worth...? I think so. I posted 2 340s made 1 day apart and the latter one had a lower number. Thanks for your input!
