And when I a kid, my brother had a 340 Demon. He built the engine and took out everything and everybody. Big Block chevies... didn't matter. As I've stated, the 340 is an awesome engine. However, was the mentality that lame that folks couldn't see why a 3100 lbs '70 Duster with 340 and 3.55's could take out a 3900 lbs '70 Coronet 383 with 3.23's? lol....
