[V8] 3.6 to 4.2 swap

[sdewitt at stx.rr.com]

There is some 5 speed specific stuff on the manifolds and TBs for the 5 speed, so got with the 5 speed manifold. Rumor has it you get a few extra ponies by using the 5 speed stuff (make sure to use the 4.2 injectors) on a 4.2. I've never done this but heard from a gent who has done this a couple times. Maybe Bruce at the the German connection or whatever it is knows something.
