On a 3.8 993 RSR I set the redline @ 7500 with the aftermarket rods and custom aged bolts for reliability(it actually saw a few overrevs of over 8000 rpm without failure). I personally would choose a cam that would peak at approx 7300. With a lighter reciprocating package I could increase that rpm limit. That engine ran a GT3 crank and SC dimensions for the R&R A-beam rods.

The above build will give you pretty good longevity.
