Depends on the person. IMHO that is getting a bit more duration than I would want for a street 318. To me 220° @ 0.050" is about the max for a street 318. As you are aware a larger displacement tollerates or likes more duration and lift.
Personal preference and expectations vary widely.
By middle ground I meant below that is more RV type cams and above is getting more street strip type cams. It’s kind of crossover point it’s not quite rv and not street strip.
