point well taken and I don't have a good answer, other than "everybody" tells me NOT to use a stock pan (engine is a 360 block with 4.125 crank = 427 cu in, hyd roller cam, IMM max ported heads with super victor intake)....so the engine is not stock, maybe that's why I shouldn't use a stock pan??? I asked the same question and got yelled at by the guy helping me with engine assembly!
