Focusing on the 284/.484 that was on a 108 LSA it has 68° of overlap whereas the 114 LSA version has 56° of overlap.
Big difference right there.
All I ever read from MP was that they changed the LSA to make it more street friendly, have better drive ability IIRC. Obviously they were selling the 108° LSA versions to more guys with low compression, turd converters and highway gearing......mismatched and poorly tuned combos than they were to those that were competent in putting together a cohesive combination.
