Hey camaro89rs355,
Emphatically -- FORGET the other mods get a 3.42 POSI in as soon as you can what on earth can you do with a 355 and a 2.73 OPEN diff ? Talk about not putting the power to the pavement.
After that ? Cold air, tune the engine -- make sure you are getting stock or better than stock numbers out of the setup. Why spend cash on bolt-ons when your coil is putting out 1200 volts at WOT or your O2 sensor is reading low ? Etc, etc.
Exhaust is easy power and sounds great as well.
my .02 cents worth,
RP.
