Hears what milodon says.
Big Block Mopars need more oil pressure and a larger amount of oil than most other engines, that's just a fact !
Higher RPM or bigger cubic inches increase the demand on an already marginal stock system. Get the right stuff the first time and life will be good.
External oil systems allow the bypassing of irregular and restrictive stock internal oil passages. These systems allow the placement of the pick-up in optimum position, plus the use of free flowing braided line. Milodon Oiling Systems provide the optimum in oiling for all types of applications and competition.And yes there is a big difference between the internal and external systems.
