modified firing order big block

I have to admit this is a subject I don't really understand. The 302/ 351 Ferd is a good example.

It would seem to me that IF the intake is properly designed, and IF the exhaust system is properly designed, there would be no power gain from either method. Remember "back when" some guys were experimenting with 180* headers?

(You just THOUGHT Hedmans were hard on the ground LOL)
