piston question
 

what up fellas. look i wanted some 9.1, 81.5 mm pistons so i asked for a set of these in wiesco and i get them. when i look up the parts number (km41m815) i realize that wiesco dosent make a 9.1, 81.5 for a ls. what they make is a 8.3-8.6, 81.5 mm. depends on the decking height but if its stock like mines that puts me at 8.3. now correct me if im wrong but this is real low right. im trying to hit 450 on pump gas with a fully built ls (stock sleeves) t3 60-1. built head. will i be okay with these pistons or not

damn

youll be fine
just add a couple more pounds of boost and pull another degree out of the timing
its all about the tune
