X2....don't forget to take care of others things like oil and filter change, clean the engine bay, fuel filter change, spark plugs, etc. Mod'* should only be undertaken after you have ensured that normal maintenance items are taken care of.

Thanks for the hints! I just rebuild he whole top side of engine when i got car, got it for 500 bucks cause the intake was leaking coolant into oil so all of the regular maintance stuff is done. I found the 3.5 pulley and shift kit on 3800 Performance - high performance aftermarket car parts for your Grand Prix, Monte Carlo, Impala, Regal, Bonneville, and V6 F-body!! is that a good place to look for stuff?

ya they are good but expensive you can get the same stuff from INTENSE-Racing.com - Pontiac G8, Grand Prix, Bonneville, Regal, L67 3800 Supercharged Performance Products, Mods and Tunes. and ZZ Performance cheaper

All 3 places are good, but check all three when buying something.
