From what I've been able to find out , the new 5.0 DOHC V8 is not a MOD based engine. Most importantly, the bore spacing has been increased. It was the MOD's bore spacing that kept its cubes (and therefore N/A HP) somewhat limited in spite of its physical size and weight. The 5.0 "CAMMER" is an expensive race piece and is not related to the new 5.0 Mustang V8. Having watched the development of the MOD engine way back when, it was called a "modular" engine in that it could be made in various configurations/displacements by simply adding extra cylinders. Initially, it was to have 6, 8, and 10 cylinder versions; but the V6 was never developed. Interestingly, Ford has their hands in several new V8 projects: The Ford 500 NHRA funny car engine, the new FR9 NASCAR race engine, the new 5.0 DOHC V8, and the new 6.2 SOHC V8 going into the Raptor truck. IMO, all of these engine projects are filling a long awaited "wish list" for Ford fans.
