Question SDPC 413 LS2 Shortblock???

Hello guys & gals.

In GMHTP mag I see 413 stroker kits.

Anyone used one of these to build a 8.7-9.25:1 CR Turbo or Supercharged engine??

How exactly do you plan on getting 413 cubes out of an LS2 block.

I don't think ANY builder recommends going over a 4.0 inch stroke with FI in a stock block. The pistons get pretty short and liner support at the bottom becomes an issue.

Yeah I would stick with a 4.0" stroke just from what I have seen/heard. But Im sure a 4.1" would work fine as well. Just heard the longevity may be compromised on those, especially in forced induction.
