I wonder what the criteria is for this, location must remain the same etc.

NHRA made the change to a solid axle conversion legal several years ago. The GTO is a great example of that. I'm not sure of what the rules are on this or how the Magnum/Charger stock rears are attached, links, spring/shock set up.
One thing with the GTO was the engine was proven to be competitive at it's HP rating, where the street 5.7 hasn't been raced much under NHRA stock rules to show what it can do. I compared the engine BP specs, the 5.7 Challenger motor is quite different, street motor c.r. 10.5 to 12.7, cam lift .482/.470 to .602/.569, different heads. Some big numbers there.
