i dont think youre gonna more then double the hp with just those, theyre all bolt ons. Minus the supercharger, all of the intake and exhaust mods might add 50 hp despite what the companies who make them claim. Then the supercharger is usually a 45-55% gain depending on the application. Considering those cars have no balls from the factory id say it should be very capable of 500hp at the wheels give or take a little bit.

Also if youre friend plans on doing all of that, he should look into upgrading the fuel system. I dont think the factory fuel system will support that kind of power.

is the pro street... can someone explain why there are flat tops, 4.5cc dish, etc and what they are for...

If you don't do some internal work on the mottor before the mods, you will after and not in a good way. You will also not get your moneys worth from the bolt ons with out going into the motor. Just some food for thought. :2cents:

Correct me if I'm wrong, but:
Domed - Higher compression
Flat top - High/standard compression
4.5 cc dish - standard/low compression
10.5&18.1 cc dish - lower compression

When you're runnning a blower or turbo, a lower compression motor is better so you can run more boost on pump gas. Higher boost and a lower compression will give you more power and safety (from detonation) than a high compression and low boost scenerio.
