71 valiant engine build, which carb to use

Who manufactured that cam and what's the lift and LSA? Those advertised duration numbers look like they're measured at .002. In the modern fast rate cams, those numbers would equate to advertised numbers somewhere in the 276-292 degrees of duration zone. I hope he's got some fairly deep gears, the compression is a little lower than I'd like to see with those kinds of cam numbers.
