[V8] 5 spd conversion: 3.6 vs 4.2

Beats me.  Operative word was "might".   My subjective thought process includes cam choice (the 5-speed cams vs. 4.2 cams vs. the 5-speed cams in a 4.2), the ABH/PT ECU choice (no difference?  How come Ned's chips aren't interchangeable?), and various components of the later wiring harness that may improve overall efficiency.

I recall a seat-of-the-pants comparison by Keith of an ABH'd 5-speed and Steve's 5-speed'd ABH and there being a noticeable difference.

Of course there's other subjective considerations too -- If I found a '93 with a bad trans, I'd swap my manual over (for a couple-few thou) but also swap much of my interior over as well.
