i have to give my 2 cents as well...

I have a SuperCrew with a 4.6L and a 3.73LS Rear...my grandmother has a newer model Ram with the 360 (5.9L V8)...my 4.6L will run circles around that thing...

now give those trucks a real test...hook a trailer up to em and see where they get you...i'd rather have my 4.6 than that 4.7...
