There's the SAE paper (authored by Chrysler) showing how effective the foam is

In SAE paper 1999-01-1785 said "8pcf density gave the best strength to weight ratio." That would be best for rocker panels and frame rails.

Looks like the foam is maybe only a minimal change...

Wood that fit the longeron tightly on the other hand would probably do wonders. Resistance to crushing (maintain the round section) under load would make it MUCH stronger...

Some tests would be interesting.
