the rods are fine, its the rod bolts that are a problem. get arp's if you plan to rev over 7500 rpm. also, the stock ls pistons dont have enough valve reliefs to clear big vtec cams, or cams that are advanced. if you pull apart the bottom end, a set of itr/ctr or even b16 pistons is a very good investment.

ls rods will happily support 300 hp and 8500 rpm, the problem with ls rods is the rod bolts, and if they've been replaced by arp's, you're fine.
