Default reving your motor out

Everyones opinions on this may differe but I usually try to stay under 6200 on stock stuff. With cam, springs and pushrods I usually rev out to about 6500 and have gone as high as 6700 when I was N/A.

Spun my 180K mile 5.3 up to 6700 and it still had good compression when I pulled it.
