Cams for 318's

My uncle Wesley had a modded Chevy six back in the day, and my friends wife has one in a 50 Impala with aftermarket intake. That being said, another friend had a 69? Chevelle, 396, 4 speed, 850 cfm Holley, ran 18's in the quarter. You just don't know...
They didn't have Impala's in 50.
