1) It's anyone's guess as to what power you make with "CNC'd heads" and a "custom grind cam". That really doesn't give us any info as far as the heads and cam go.

2) Ditch those shitty SLP shorties and get some quality long tube headers. That in itself will yeild a huge gain. Ditch the cats and get yourself an electric cutout.

Default tranny

just so you know the t56 tranny which is the 6 speed in your car is only rated for 500 hp so my suggestions for u tranny wise is either get the tr66 tranny which is the viper 6 speed if i remember right and its rated for 1100 hp or 1000 hp i cant remember but you could put the viper kit for the tranny and itll make your t56 rated for 1000hp. thats my suggestions to you the viper kit is cheaper to do so which ever you want.
