That and the fact that the 94-98s just don't breathe well enough (neither the intake tract nor the cam) to make power at anything more than 5k-ish. The torque drops off like mad above 5k. 99+s breathe better, we don't start to drop significantly until 5.5+k.dastang2 said:i think the reason th 94-98 v6's had less or a rpm range is because the lack of the balancer shaft. i have a 2000 ford direct replacement engine and it has the balancer shaft in it. so i think i am good on that.
