Generation IV Internal Engine - L92/LS3 sleeves can they be replaced

just as the title says can they be replaced as they dont have a step bore like the LS7 sleeves
any info would be great

There are company's like erl that can resleeved it.

Any automotive machine shop can resleave the block. They can go back standard bore or oversived. 4.1 bore with a stock stroke crank would get you 382 CI.

thanks for the input guys

The LS3 L92 blocks can be sleeved using Darton's LS7 Seal Tight dry liners. Actually any Gen IV block can be sleeved using these liners. I have sleeved hundreds of these blocks.

Bore size range is 4.125" to 4.185" with max. bore NA only.

Sleeve length is 5.800" for better piston support with long stroke cranks.

Note that installation of these sleeves can not be done by just any automotive machine shop. You need a flood coolant CNC, stress relief equipment, and experience to hold the tight tolerances required for a successful installation.
