150-175 Wet Shot
? 
Both the engine and rear-end. If not you will be very lucky. With your cam you'll be sucking more fuel than normal. Add the 150-175 shot, and do you really think you're going to be safe.
Along with the 150-175 wet shot, this is what I would suggest: 30# injectors, Racetronix drop in fuel pump (they make them for 98's www.thunderracing.com ); save up for a 12-bolt and converter. Have it tuned for both engine and nitrous (2 separate programs via LS1 Edit).
If you intend on any type of launch off a stock verter, on a stock rear-end, on slicks good luck.
