Well I don't think you quite understand, designing a completely new 32-valve engine that "happens" to be 5.0 liters in displacement is VERY different than "taking the old 5.0 and giving it todays works". The new 5.0L shares NOTHING with the old 5.0; it is not an "update" of the original in any way it is a completely fresh, new engine design purposely made to 5.0 liters because of the marketing potential which has worked... The engine itself is a powerhouse BTW it is in a completely different class of power and efficiency than the old 302 windsor could ever have been brought up to. An example of a redesigned engine: in the early 1990s the truck market was becoming more competitive and Dodge needed something to bring it up-to-date. They knew a completely new engine design would obviously have the best results but based on what was needed at the time COST was more important. Hence, the 5.2/5.9 Magnums. They share the same architecture as the LA but with redesigned heads, roller cam, pedestal rockers, EFI yada yada but those are all rather minor tweaks when compared to a new design; they can swap most parts with the LA. The 5.7 Hemi shares a 360 stroke and 318 bore for ~345 cubes but shares no actual parts with those older engines.
