I'm replacing my 302 in my 72 ford econoline E100 van with a remanufactor.It had in it a 1980 302 casting # EOAE D3C(D-11 engine). My question is what's the difference between a DF-11 and a DF-46 302 engine,I search internet and can't find anything. (only thing I could find is the df46 price is lower than df11)
