You still have not responded to my question. How is it any different from what everyon was crying about 8 years ago when the 4.6 was introduced? They should keep the 27 year old 302 the R&D was already done.... There won't be an aftermarket for the new 4.6.... The 4.6 won't have interchangeable parts to my 5.0.... Your argument is 100% flawed. It is the EXACT same as the 4.6 VS 5.0 debate from nearly a decade ago. You stated that your argument was different then that one, now PROVE IT!
