What is the optimal rpm for a 500hp (carb 1998)

Fooling around with props and would like to know what the target rpm is?

On the 97 HP500 WOT is 4800 - 5200rpm. Should be same.

Ap I guess when you have a choice of running5200 rpm with a 30 or 4900 with a 32 (in my case that is). Either prop would be ok. The other things I guess to consider would be hole shot and mid range speed (when I went from the 28 to the 30 made. Significant mid range speed improvement)
