The 6.4 had a limited run so parts and expertise will always be harder to find. For a while, Ford did not use 19.5" wheels on the F450 pickup. This is only an advantage if you go places where you need to air down tires for flotation or you drive the truck unloaded often. The 450 pickup uses a 350 frame and pickup tuned engine but has the chassis cab axles. As far as I know only the higher ratio axles were used at 4.30
