How much Hp will the Callies Compstar LSX crank, Dish diamond pistons, Ultra H beam rods handle at the crank? The build will be for a boosted application.

I have many. A bit overwhelmed with choices, cost , and what I would actually need. I have a very low mile (18k) 2010 camaro 2SS, 376 cu 6.2 L99. A 6 , have some bolt ons, root fab cai, SW headers, corsa extreme 3”SS . I’m ready to start adding power and rotating mass reduction.
