100 Stock bottom end, haven't even had the heads or intake off yet. Like Call911 said, you need a good tune. I am even running a little leaner than most tune at, she is at 12.0 across the board. If the car sits for awhile, I will pump the fuel out and put fresh in. I run 93 with Torco Accelerator additive, about a can to every 10 gal.
Before the supercharger, I did a dyno test with old fuel and then new fuel...19 hp. I got 14 back with NOS octane boost. And by the way, you can't keep the Torco stuff from season to season....she goes bad!!
Fuel system, no matter what boost....get a good pump in there.

Safely with a stock bottom end, and everything I listed above, I wouldn't go above 6#'s unless you are ready to buy a new block if the stock one goes.
Just my .02 cents. Everyone has their own opinion on this.
