I heard from a guy at Self Racing that he sleeved the block & used custom pistons (a call to Darton confirmed this). What bore size he went with, I'm not sure. The stocker is pretty small at 93mm, or 3.66". I'm going to use lower compression pistons & let the boost do the work.

Sorry- I don't have a list. I'm trying to piece together what I can from the guys who've done it.
