The Performer RPM cam says that lower than stock rear gearing and high performance torque converter is necessary....Why is this? And it also says that 9.5 comp ratio is required and I do not know what compression I have. Was planning on putting RPM heads on too. Can the RPM heads and RPM intake be used on a standard Performer cam? How well with that match up?
