I will put your theory to the test soon.
I'm replacing my springs on my 72 340 4 speed Cuda .
My experience has been in my 2 340 4 speed cars as soon as I rebuilt the motors greatly increasing torque and hp I had axle wind up issues with the 3rd member hitting the floor .
I never had problems with stock engines .
I do know my friend used super stock springs and still ran a snubber .
I guess opinions are like assholes , everyone has one !!
