360 vs 383

I wonder why the exact reason(s) they ditched the 383 and went to the 400? I know the petro embargo and all, but the 400 wasn't about mpg. I can't imagine they thought it would be better for the EPA. Why?

Probably to have a competitor cid wise with ford and chevs offerings around the same size and probably also distance it from the 360 more.
