Not Ranked
I am running a performer rpm on my explorer motor with GT-40p heads. It pulls great from almost Idle up to 6k where the cam has already started to loose steam. The Performer RPM (and RPM air gap) and Weyand Stealth are good to 6500 rpm and they will produce a little more torque down below 4000 rpm where most street driving is done.
IMHO unless you are building a 7000rpm screamer go with a good dual plane.
