73 Duster build named Fred

Good to know. I'm not sure what my builder's range of comfort is. Curious to see what the clearances are on the entire build. .120 seems tight to me but I am probably more cautious than most.... lol
I have around.110 with my big block now, it was closer before around.100 and no issues
But It didn't go passed 6300 and it was on the Dyno 50 + pulls
