I was told to running a cooler plug with my supercharger. Does anyone know the part number and suggestion for a brand?

Usually you can ask depending on brand your local auto parts store for the stock heat range and then just ask for 1 or 2 heat range colder.
GOD...i would hope they knew what you were talking about... ![[Roll Eyes]](rolleyes.gif)

sorry i don't know the exact # you want but i'm sure someone does but like i said it would depend upon BRAND

If there stock heads use Autolite 23 which is two heat ranges colder than the stock autolite 25. Don't forget to gap them at .035.

Since there trick flows it does change. The stock plug should be autolite 3925 or 3924. What most people run are the 3923 gap around .032-.035 and lower your timing from stock to around 7 degrees initial.

Is the lowering of the timing because of the autolite 3923 or is it just because of the blower?

Because of the blower, be sure to use anti-seize oin the threads

Because of the blower or turbo or NOS. You do not want to run lean with any power adder otherwise you will be replacing head gaskets. A proper tune is important. If you do not know too much about tuning with a supercharger, I suggest to learn by reading info on the corral or any other forum under Superchargers, just to get the basics down so you don't blow your motor or gaskets.
Goodluck
