400hp at the flywheel? or wheels? And Are you going to use all motor, or are you going to spray, or a supercharger?
If your using factory rods, that havent failed over many years of use, you no theres no defects in them. I would say they could hold 350 HP at the flywheel no problem. I would ask a machine shop, for advise that builds them all day long, sence no one else has replied but me
Spraying is hard on motors, i wouldnt spray to 400Hp on stock rods. stop me if im wrong anyone
