Just found a comp cams 20-230-4 274/280dur 502/511lift would this be a better cam?

And a mopar purpleshaft but i cant find any info on it its got a white stripe and a yellow dot with numbers 202136 stamped in it

I am no expert but seperation is most important on the camshaft. Low duration is second and lift is last.
