For some reason, the '96 Vortecs were really strong motors... It will respond well to your planned mods! With all of the mods listed, you are probably looking at 50-60 hp (w/o 100 shot, of course) advantage... The stall will help the most, eventhough it doesn't make any power... Just make sure you do long tube headers... And a live tune is recommended. And you WILL need to do some tranny work soon. Trust me.
