Are 340’s rare

Short stroke 340s have HEAVY pistons, HEAVY. 4 inch crank small blocks have short very lite pistons. Like I said earlier my 414 revs way faster then my stock 340 ever did. If I stomp gas pedal to the floor the 414 will scream up to 6,000 rpm faster then it takes for gas pedal to go down, like fraction of a second...
