Welcome to the site, not sure what you mean by a 6 vortec. If you mean 6.0 then the piston size is bigger then a LS1 already. If you mean V6 then I dont know what you are trying to do.....

Welcome to pt.net, I hope your swapping from a 6 banger to a 5.3L. That'll be a fun project, especially with the bore. Have fun!
