Camshaft id please...

That Crane SS 320 is going to be a BIG solid flat tappet, unless it's been reground. Probably on the order of 320/330 advertised duration. I had an old SS 310 in a Chevy 396 decades ago. It was 310/320 .600/610 ground on a 108 for comparison. But remember, the big Chevy had 1.73 ratio rockers, so the Mopar small block version will have less lift, but I bet I'm spot on on the duration.
