what parts do i need
 

what things can i do to my automatic fb to up the power w/o putting a 5-speed in it?

supercharger,turbocharger,nitrous:D

What about an exhaust setup. A freer flowing exhaust with some other small things should make it feel a little faster. Another thing would be to go with a Racing Beat weber or holley carb setup. I guess they really make some nice power when used in conjunction with a RB exhaust. A little expensive, but well worth the money.

Personally, I went with a custom exhaust. But I also have a 5 speed and don't know what the autos are like.
