That’ll have a mostly smooth idle and make OK decent power. I ran a very similar Crane cam in a stock long block ‘79 - 318, 904,w/3.21 gears, hooker headers into a Jegs dual exhaust, LD4B and a 600 Holley. With regular stock sized tires it could get into the high 14’s easy enough. Traction was an issue.
You should be able to pull down 17 mpg’s or slightly better and better than I did in the 1/4.
