Keep hearing about frame twist with 440s

Chassis science has come a long way in the 50+ years that I've been playing with cars. Back in the mid 60's a guy in my area ( nick named Froggy) shoe horned a 413 industrial engine & 4 speed in a 64 Valiant or Dart (don't remember which). On the crappy street tires we had back the, he twisted the body so bad that the doors popped open & would never close again. He found another A body, tied the sub frames together & shoved the motor & trans in it. Problem solved! LOL
