Default LS Stroker Kits?

What displacement increasements are available for the LS1/2/3 engines in regards to a forged bottom end? Not considering boring the cylinders.

My friends have done alot with their LS engines and everyone that went forged just went with either an LS2 or LS7 block. I know a guy running 950 whp with an LS2 block and a stock LS6 manifold and throttle body. The key is his 91mm Turbo. If you want to go all motor stroker is the way to go but I have not seen or heard of anyone stroking an LS motor.

I do know that you can get LS2 blocks in a 402CI

Yeah, that LS2 402 IS stroked, to 4". This is standard stroke for a 427, too. Also gives you 382CI on a stock bore LS1-6.

Yes, but my scanner is down - it showed 458 RWHP and, 438 RWTQ . I have the mildest of the three cams they can put in this setup. Not like some of the monster forced induction motors but strong and lots of torque - about 80% of maximum torque at 2500 RPM's.

Very nice there! That's about the output of a C6ZO6. Do you remember what bottom end parts are in there?

"So much torque, the chassis twisted coming off the line."

Shameless F&F plug lol.

Anywho, man I love the setup you are running there. That's about exactly what I want. I am guessing this is a weekend toy correct?

How is it in traffic?
Can I ask how much that setup runs, plus the tune?
What's the maintenance like?
How many miles on that setup?
