Less static compression and more boost?

My last motor was the LS2 block/LSA head deal. Compression ended up at 9.1 and 364 cubes-it made 1000 rwhp and 850 rwtq.
It was no dog putting around town or the track. For a d/d the lower compression is great on pump and meth.

I would run more compression with more cam and a tight quench with Meth. And pay more attention to the Dynamic compression than the static compression ratio.

I mentioned in my original post that I intend to go with a stock displacement LS2. The reason for that is for every example I find of a problem free stroker motor, I can find an example of excessive oil consumption, short lived piston skirts, increased cylinder wear, etc.
Outside of chamfering the bottom of the cylinder and selecting the right skirt design, I don't know what else you can do to address the inherent lack of piston support at BDC. It would seem that some builders have figured out what it takes to make stroker motors last but I don't know what kind of success I'll have. I could sleeve the block but I don't know if I'm up for the added expense.

Arun, I know you've previously ran a stroked LS2. I believe a 402? Why did you elect to go with stock displacement with your last motor?

It was more fun on the street and it went 8's first day out at the track-with the 402 I was always having trouble getting the car to hook.
