My preference in a hot rod, or something that's going to be beat on, is a 904 when built. In stock or driving "as is", 727's are much tougher in stock form.
Amen the 727 is the king of course I mean it was behind anything from a half ton jeep truck 4wd to a large dual wheel motorhome but a 904 can be built easily to achieve 7,s in the 1/8 minus big sticky's and large converter in heavy vehicle.
