Automatics can be very stingy hitting 400+ RWHP going cam only.* If you did cam only you'd have to go with at least a FAST 90/92 intake with a big cam. Maybe an electric water pump to free up some ponies. Just go Heads/Cam/Intake so there is no shadow of a doubt that you will hit it.

*Disclaimer - Yes, it can be done with the right supporting mods, proper cam selection and an excellent tuner.

Lid, ud, smooth bellow, pp tb, lt headers true duals or catback .....go with a good medium cam like a torquer2 or 3, 231/237...233/239 ....should get you around 390-415hp in a ms6 ...more will be needed. To autos..
