Mopar 284/528 mechanical camshaft

If you think the 284/528 is old school get this, I had the early version of that cam in my 340 when I first got it. It's the same basic cam but it had about
.540 lift. Still was a good cam. In a subsequent rebuild I went with the MP
.557 lift cam but didn't really see any appreciable gains. Now the .590 cam is another story and it performs well too but my Hughes (Engle) 278/.630 -
288/.630 cam was 2 tenths faster, both using 1.6 rockers.
