At 450 rear, about 550-575 crank with my procharger and mods, I am exerting 37,000psi stress at 5500 RPM (max power) so these rods could easily handle 6-700 horse. The S-N curve for these rods have infinite life at under 42-45,000psi stress, so as long as you keep it under that stress for less than 1,000,000 cycles you're good. 1,000,000 cylces is like 3 hours of driving your truck wide open!! Not gonna happen. So these rods are plenty strong. I swear I just had a presentation on this two weeks ago, haha.
