363ci Stroker kit for L33 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.

If I did that the block may actually make to 2 or 3 more builds. Stroker kit seems appealing to add torque.

5.3L Shortblock from Texas Speed
I saw Texas Speed sales a Shortblock close to what I'm talking about building. I can build a close copy to that short block using my L33 block for about $2500 with the Eagle Stroker kit and Machine work.

Nobody has a LS2 around here and if they do they want a arm and a leg for it. If I go all forged I will have a solid foundation. This L33 will be like 1 cubic inch short of a 364ci 6.0L if I go with this Stroker kit and it will most likely make more torque than a 6.0L with a 3.622" crank because the L33 363ci would have a 4.000" Stroke. The small bore combined with a long stroke with high compression should create a high velocity flowing engine using the Katech 215cc/82cc Cnc Ported 799 Heads. Valvetrain would also play a big part also. L33 is 109 lbs lighter than the LQ9/ LQ4 also. I do not want an Iron Block. But I'll take a Tall Deck LSX Block

Take that 5.3 out to 3.905” and build a 383, they make surprising power, bore it to 3.903-3.905” and get a 383 rotating assembly, you’ll make way better numbers with the larger bore. My first LS build was a 383 from a 5.7 block it made 517rwhp SAE corrected with hand ported 225 Dart heads. I say this if you can bore that block .123”over, my current 347 is an LH6 aluminum 5.3 bored 123” over, so some can be taken way out.
Do some research on a 4.0 stroke and you'll see differing opinions on them, I have a 408 (4" stroke) and went that direction because I don't expect to put a lot of miles on it so life expectancy isn't an issue for me. Many builders will steer you away from a 4" stroke in a stock block unless the trade off is worth it. What is it going into? Sometimes the extra torque with a stroker build isn't needed when you can build the same cubic inch engine without it by going with a bigger bore.

Let me make this clear again, I dont want to Take all the bore sizes out of a perfectly good block all at one time. That is retarded. Yeah I could bore to 3.905 " but that would pretty much be the last bore size for the block.

I have a ruined LS1 block because something happened to it on its last bore size. Gen 3 aluminum blocks will be hard to find before too long. Everybody buys them and bores them to the max then blows them up and then the block is a coffee table. That is wack as hell. You only take off as much material that is needed to clean the bore up if possible. To me 0.020" is alot to take out at once knowing it only needs about 0.005" to clean it up. Just saying.
It would be nice if someone out there made new sleeves to extend the life of these blocks...
They won't be any harder to find for the next 10-15 years then they are now, Most are still in cars being driven daily and they will likely never be rare.

Really? How many L33s do you think GM made?
As far as I know they were only offered in a select few 4x4 trucks for only a few years. The rarity Of the L33 will continue to go up, Racers want them because they make Awesome Turbo Builds, Country Boys want the whole Truck so they can go stick it in the mud and tear it up, or flood it out. In 20 years you'll be finding engines from 2019 in the junkyard. You wont be finding any LS1's or L33's and if you do it will be a miracle and a blessing. Lol

L33's are Gen III. The aluminum Gen IV 5.3 blocks are the LH6, LH8, LH9, LC9. Lots to choose from. AND they all came with the much better Gen IV lower end parts. L33 ain't the only game in town. Comparatively by numbers, it's a minor player.

L33 comes with all the good stuff the Gen 4 has as well, Anyways if I go forged that doesnt matter.
L33 doesnt need the VVT delete, L33 doesnt need AFM delete. L33 is holding multiple records right now using stock bottom end with Turbos. Why would I want another player? Lol I have a MVP on my hands.
