I would just do offroad exhaust (x-pipe), intake, and tune to start out. That's probably good for 35-40 rwhp. Then add the cam and headers down the road for the big bang.
The dyno numbers above show the actual power gains from two separate Camaros. This calculates to...
The manual picked up 40hp at the crank.
The automatic picked up 43hp at the crank.
This is a 10% improvement. That is a good result for basic components.
The MTI Racing Ignition Wires are perfect for cars with headers. They are slimmer at the plug side so they are easier to reach in with your fingers, and the silicone is made from a much more heat tolerant silicone. The imbedded fire-sleeving also protects the wire from heat, keeping the ignition higher during higher underhood temps.
The lower temperature variable thermostat also helps coolant temps and fan operation.
