The Crower catalog list the rpm range as 2500 - 6000 rpm with a red line as 7500 plus. It really starts pulling well at 3500 and will continue coming on strong beyond 6000 rpm. My rev limiter is at 6500 rpm so I don't know what it will do beyond that but it was still pulling right up to the 6500 rpm limit. My carb is a Holley 750 double pumper with mechanical secondaries and the intake is Ford aluminum Boss 351 dual plane. CR is 10.25 with a GTS exhaust. I wanted the biggest cam I could get and still pull enough manifold vacuum to run the power brakes when idling up to a stop light. I think the manifold vacuum is around 8 to 10" at 800rpm. It idles better at 1000 to 1200rpm though. I am in Colorado at 5000 feet plus elevation so you guys at sea level should do even better.
