Best Nitrous Kit Looking to make a few changes on my car before the Car Craft Summer Nationals and am wondering what the "best" most complete kit is for an LT1. Looking to do a 200-250 shot.

I would also look into upgrading your fuel pump and bigger injectors.

Why would you need bigger injectors with a plate system?
IMO "best" is a term too rarely defined. There are multiple ways to achieve a goal and often several of the ways have substantial merit.
IMO you will also be hard pressed to find a good complete "kit" for a shot that large.
For that much spray I would be looking at a dedicated fuel system.
The true total cost of a well setup nitrous system is FAR higher than the cost of a kit.
The above linked kit is better than most but instead of the included window switch I would use something like the Mallory 685 which not only does the window switch but the timing retard and spark based rev limit.
I will assume the bottle heater is temp based, someone else offers one that is pressutre based which is actually what you are trying to accomplish is a set pressure.
FPSS are a good idea BUT if you try and use one in a system tapped off the schrader port on the rail you endup having to set the switch VERY low because of the pressure drop caused when you trigger the system can make the switch studder otherwise.
You can just throw a $600 kit at a car and spray away but it is easy to do a lot of harm that way.

I ran the plate kit on my old set up. Ran a 125 shot w/ the NGK tr6, window switch, and purge kit. Also stepped it up to 36lb injecters as recomended by the guys at Nitrous Outlet. Used the stock fuel pump which took a dump roughly 5 bottles into spraying it.
WET with a stand alone fuel system like cap said! Sprayin 200-250 is a healthy dose of gas and takes different measures to make a safe setup. Most "kits" are good up to around a 150 shot. Some may disagree, but seems more have been successful with stand alone fuel systems than others who just run a plate setup sprayin 250. Hell I know of a guy who was sprayin a bone stock lt1 with a 250, but he was runnin a standalone fuel system. It had made multiple passes down the track and runs on the street. Last I talked to him it was still runnin strong lol.

If the engine needed injectors vaguely that big then the single Walbro 255 wont feed the NA power+ the nitrous anyway. That again leaves you looking at a standalone fuel system.
There are good arguments to be made for dry but dry is easiest to accomplish with aftermarket management. It has been done on a stock computer without jacking the fuel pressure, guy uses the pcm to inject the extra fuel. When your job is to run a dyno and tune though you can experiment and take the time to set things up that would not be cost effective for the rest of us.

Any thoughts on the ZEX LT1 system, I only want a 125 - 150 shot and I like the fact that the ZEX kit monitors bottle pressure and injects the correct amount of fuel so not to be rich or lean. Thoughts on that kit?
I would stay away from that stuff! Some have had issues with that fuel/nitrous management unit that comes with the kit!
Check this out, pretty neat dry setup!

Here's there wet kits also:

I personally love the big NX noids, I'd look into nitro daves money maker kit if you want to do it on a single stage 250. While others have, running 250 through the throttle body or via a plate I'm not a huge fan of doing.
