Built motors are not bulletproof. If there is anything I want you to take away from this video is exactly that. Just because you invest in forged engine internals doesn't mean that something can't happen to damage your motor severely. I got excellent usage out of my Iroz Motorsport built motor, and will now need to rebuild in order to continue drag racing.
