Default what fuel parts will need to be upgraded?

I'm doing a 383 stroker good for around 415hp motor and I will put a 100 - 125shot of wet NOS.
On my 1995 z-28 camaro lt1
The car has 120,000 miles on it.

What will I need to replace? Fuel pump? larger injectors? what lb if so... oil pump?

Also how will the stock rear end take it ? I think it his the 2.73 in this one. Also how much can a stock torque converter handle? The 4l60 is build alittle bit...

So many things...
Get a Racetronix Fuel Pump Kit. It will come with a Walbro 255lph pump and will handle your hp needs with ease.
Get 42lb injectors.
The oil pump you use (what pressure & volume) should be decided by your builder.
The stock rear will be a accident waiting to happen if you leave hard w/ sticky tires.
Stock converter is a HUGE no no with the build you are proposing. You probably want something no smaller than a 3600 stall. Look into companies like Yank or Vig.

Sounds like you are nowhere near ready for a stroker.

415hp flywheel would be increadibly weak, 415hp rear wheel still noting impressive for a stroker.

Do gears, do the converter, do injectors and fuel pump.

Throw the Hypercrap in the garbage.

I will have nitto 275's 17's on it.

Yes, I forgot to mention, as 96capricemgr said, get gears! 3.73's.
Trust me, get a bigger stall. It won't be crazy.
What heads and cam are you planning on using?

For around 3 grand you can get a forged 383 from Golen Engines:

Not Hypereutectic pistons and cast rods like the one you are looking at. Hell the guy doesn't even know how to spell "hypereutectic" in his ad.
And come on, a LT4 hot cam, what's the point.

So you are saying that you can get the 383 short block with ported heads for $2500 shipped?
Garbage! I'm referring to the parts, not your claim.

From his description, it sounds like you'll receive a 383 that performs like a stock 350 with a few bolt-ons. If I'm wrong then I apologize. But:

cast parts crank and rods
hypereutectic pistons
"can handle an additional 125 shot or 6lbs of boost"

...sounds stock to me.

And their stage 2 porting for 300...sounds like gasket matching and a valve job.

If all you wanted was a replacement engine, than I guess its a good deal, but if you wanted a street/strip 383, I think you made a mistake.

I am not saying that you can't make power with that engine. If you swap in a real cam, you can make some nice power. It will all depend on the port work on the heads. 100 hp will be easy with the right cam and all the bolt ons. It will also help if you verify the CR. Something like 11:1 will be nice for a NA application. Add a shot if you are not satisfied.
I didn't want to knock you down or anything, I was just trying to offer my opinion of that engine.
