Sorry for the incorrent info, just checked my blocks again, my helper used a pos mic. I knew I should have checked them myself lol. My 59 389, 74 455, 67 400 are all .309, and thats 3 different gens. I have 4 sbc's early and later that have the exact same size dowels for the heads as well. Guess thats what GM was using. So yeah, i'd like to see one with .3125, I didn't check every block I own though......lol
