Keep hearing about frame twist with 440s

I figure it can be like replacing floor pans, car needs to be sitting level other wise it can sit cocked eyed after the new pans are welded in! I admit after 35 yr playing with these things I never have had a rotisserie or lift. Wish I did.
But if on the rotisserie there in NO engine weight either, it is not being mashed down anywhere, so no doubt all would be good there.
