So this is the second time "the Beast" has thrown push rods. This time #8 cylinder. My mechanic says the thrown push rods are because the engine was over reved. That did not happen. I drove no faster than 60 mph and never "opened" the motor. Push rods replaced. Running again and now engine is running cooler! I am having another mechanic who is high performance specialist re adjust the valves. Any input please? Thanks Michael
