Yes, see when increasing stroke you bring the piston further down in the cylinder which exposes the bottom of the piston out of sleeve further at BDC. This action allows the piston to rock more and eventually can lead to an increase in oil blow by consumption.
One could resleeve with longer sleeves and that helps if one is set on running bigger than 4.00 stoke.

LS3 block + 4.100" stroke would be an okay combination. 4.07" x 4.1" would get you 427 on the nose. Wiseco makes pistons for the 4.100" stroke that reduce some of the oil consumption issues. However, you end up with a thin crown on the piston, so it's pretty much an NA only setup or very mild boost/nitrous. It's only a little bit more expensive than the LS2 and a cheaper alternative to the LS7.

An easy way to decide your combo: Divide your rod length by the stroke, if the number is lower than 1.50, try and avoid it. A 6.125"rod length divided by 4.0 =1.53, still reasonable. A 6.125 length divded by 4.250' =1.44, not so much.

The rotating assembly I'm looking at is the new kits from Wiseco with K1 cranks & rods-unless somebody think's it's not a good product/kit.
