The LS2 kits will not work.

We have the small(er) bore block. Our crank is 13mm shorter than a LS crank. Cams and intakes will interchange.

Your closest application would be pistons and rods for a truck 5.3 with a custom stroker crank.

Theres been talk about it , depends on how big you wanna go , the crank can easily be machined to our needs.

And also depends on how deep your pockets are.

Minimal displacement increase for the money. See how much a custom block is if you have cash to burn.

I made a post about this when I had my SS and I was told that having these engines bore and stroked were useless unless you were planning on spending massive $$$. Get the 5k turbo kit, a cam, beef up the transmission, some ported heads, the ls6 throttle body, some headers if you don't have them, and a hand held tuner. That would be a lot less than getting this engine bored and stroked

Would new sleeves alleviate that issue? If so, how big can one go on these motors? They were available in both Gen III and Gen IV configuration.
