A question

I agree with the flapper. The 440-3 in the motorhome that my father and i co-own had a red hot right side manifold at night one time. It made the motor so hot that it fried the ignition coil. Well, i wired the flapper wheel into the open position to hold it. Lol, the next day(and i we have 3" flowmaster exhaust on it), i revved the motor in the morning to kick down the throttle on the carb and i heard something shoot out of one of the tailpipes. It was the damn flapper. Good thing i have less restrictive mufflers, or i would have had a problem trying to get it out. :sign6:
