another way would be to put your car on a chassis dyno, and examine the power curve, and see where your power begines to flattenout. For my stroked Windsor, it is about 5600-5800 rpm. So i have a 6000 rpm chip in my rev limiter, and a shift light chipped for 5800.

Like the others above comment, higher than necessary rpm is really stressful on a motor. I can't afford a blown motor, so i don't rev mine higher than 6000, and rarely go that high anyway. On your motor, if it were mine, i would not rev more than 5500 rpm.
