Yeah, I believe I'm going to let the 5.3L Baby LS6 Eat and throw the 382ci Stroker Kit in it. Paired with the Cnc Katech 799s, Cam Motion Custom Grind and fed by the Fast 92,LS2 TB and 46lb Fast Injectors should be a Super Healthy Combo. Hopefully 480-500 Rwhp
I'm sure ill have to upgrade from the LS7 clutch. Lol

Look forward to seeing the results. You can definitely make those goals. My 383 (90mm TPiS LS6 intake, TEA S2.5 LS6 heads, a small obsolete 229/229 cam) made 465whp. 
Winning...a Walbro intake 340 and 60lb injectors would get him to 600whp for a fuel system on the cheap.

I just ordered the same kit with a 10:3:1 compression
FAST 102mm intake and throttle body.
Comp cam and valvetrain upgrade.
FAST XFI standalone with racepak street logger.
I did the same bore .20 over to leave more sleeve for better head gasket seal and future rebuilds.
Should be tuning on Dec 1st at west tech so i will update you when I'm done. It's going in a s13 hatch fully caged and gutted.

I'm looking into getting a 363ci Stroker kit from Cnc Motorsports, Corey said he can get me :
-Eagle Forged 4.00" Stroke Crankshaft
-Eagle Forged 6.125" H Beam Rods
-Mahle Forged 3.800" Flat Top 2 VR Pistons
-Pins,Locks,Piston Rings
-King Rod and Main Bearings
Anyone had any experience running a kit like this?
I am keeping the bore small to reserve cylinder life for future rebuilds. I have a set of Cnc Katech 799s, Fast 92 Intake,LS2 TB and Fast 46 lb injectors.
Cam choice will be Cam Motion Custom Grind
I'm hoping the Stroker kit would add some more fun factor to the Combo, let me know what you guys think.

With very few exceptions the 363 kits and short blocks are basically pogie bait for the ignorant and naive.
The 4 inch stroke 3.80 small bore 363 is possibly the most poorly optimized of all LS engine builds. All of the cost of a stroker with almost none of the benefit. It's hard to imagine a worse bore and stroke set up for NA from what I've seen in the LS world.
In NA bore is far more important than stroke to make good hp. Big bore allows bigger valves, less shrouding and more flow to make mire power. The 4 inch stroke crank is less ideal for forced induction. You better make absolutely sure the correct design piston package is used otherwise that 4 inch crank mini stroker will be an oil guzzling detonation prone pig with ring seal issues.
A good 4 inch bore 3.62 stroke LS2 have more potential and less cost. It will also take boost and rpm better than a 4 inch crank set up.
Punching the L33 out to 3.903 or 3.905 and building a 383 stroker could make for a sweetheart of an engine for that C5. Otherwise sell the L33 and get another motor.
Of course it's your money and project so it's your decision.

TL;DR: WAT ABOUT WITH AN LSA BLOWER?
gd mongo & mullet motor works overhere just want to square port the world, LITERALLY THE ONLY WAY TO MAKE UNDER SQUARE IS SMALL BORE WAT IF WE WANT UNDERSQUARE BOOST MOTORS SMDH...
