Recomendations on modications??? I got a 98 WS6 (6 speed)
Its got 110,xxx miles
Modifications Now
ls6 Intake
Hooker Longtube Headers
Texas Speed Y-Pipe (Always open with cutout)
4:10 gears
If you guys were in my shoes what would you do with the car as in getting more hp out of the car?
I thought about nitrous (wet kit)
But when u start thinking about fuel pump and all the olds and ends it tends too add up with the cost of the total package. Will it stay together on 100 shot
The other idea was a cam with all the supporting mods. But my draw back on that idea was that I seen a lot of lifter failures if you go with to big of a cam. (Must be a 98 thing I'm guessing)
Or just buy a short block ls1 and do a budget build cam and supporting mods with 243 heads and intake.
The car just is here to have fun with a take to the track every now and then
With everything remaining in stock form the car runs 12.82 at 109 with a 1.8 60' on 275/40/17 nitto 555rs
With all that being said would like to get 120 mph in the 1/4

Either way, you won't hit 120mph with the current setup plus only a cam. You would need more power modifications in addition, or some serious weight reduction.
It's not a hp mod but I'd start with the rear especially being a 6 speed. No sense in breaking the 10 bolt everything you race it. After 3 times I finally got a 9". But to answer the original question I'd vote cam just for the fact of the power always being there. Also sounds alot better. Then spray it

Yeah i thought i have heard about lifter failure. But yes i always hear about rod bolts being a issue. Would the stock pump withstand 100 shot (WET KIT)
Or is the dry kit the better way to go and change injectors

Unfortunately there is nothing budget once you start building a motor from scratch. A 100 shot is relatively mild, but a better fuel pump is cheap insurance and not much more of an expense as compared against a complete motor build. Also, if you do a search, there is the "trap door" method of installing a new fuel pump that eliminates dropping the whole fuel tank.
I would put a clutch in the car because it will need it if you're not already upgraded.
From there I would go cam for sure. Power is ALWAYS there and it just sounds sexy...Filling up bottles all the time gets old AND expensive...Ask me how I know
You DO NOT need fuel upgrades for a 100 shot...Go with a wet kit if you decide to go this route. In order to do it right and be safe you're going to spend close to $1,000 and then add on a tune price tag if you want to play it real safe.
Get the cam and don't look back

Most full weight f-body LS1'S (including rims) around here trap 114-116 on average. I'm sure a few have hit 120 in full street trim with perfect track conditions, but I've never personally seen it
Agreed. Just saying. It CAN be done, especially if he can drive it with that gear.

I have never seen a cam only, full weight 4th gen trap 120mph with only headers + exhaust, LS6 intake and 4.10s in addition. No reason to get a person's hopes up based on some isolated example with unknown details. Perhaps the cars you've seen had additional bolt-ons and/or weight reduction.
In general, the setup above won't come close to 120. As mentioned above by HCI2000SS, 114-116 would be a more realistic estimate.
