Isn´t that a bit of overkill considering that it is only a 318" car?
To repair rotten parts (if there are any) would make the body solid enough to handle the power from a 318".
Want more engine than that? Then a pair of sub-frame connectors would be a good idea!
If it were just about engine weight and power Chris that would be true. But even with "just" a 318 engine it is still a two ton car with a flexable chassis.
The cars basic construction was designed in the early days of American made unibodys. American cars have always used very simple and crude chassis designs which never change much over decades. Just look at Ford. Still producing cars with 50 year old chassis designs.
To make any Challenger feel "tight" on the road the chassis needs added strength. No matter what the engine size. You could leave it as it is of course. But if you are welding the chassis anyway it wouldn't be a bad thing to do.
