My dads cousin ran a 340 Duster in the early 70's around Youngstown ,Ohio. I heard plenty of stories.
I have East coast gear oil running in my veins, transplanted in Idaho in 1975.
That's cool then it should be a 9 second car Pittsburgh small blocks are nothing super fancy just a little small block.451 so the math should put you around 9 seconds flat if it's anywhere close.
