I looked at the Crate class, and it looks like the only LS motor allowed is the LS1, which is smaller (ci wise), more expensive, and an aluminum block (again more expensive). The approved LS1 pistons are only for the smaller bore LS1 not the 4" bore LS2 or LQ9 Pistons.

I'll look more at the truck class...
