Engine swap computer & wiring question

[Tim De Coster]

Yep, I see your point.  I'm not planning on using the iron heads at all
though.  I understand that the 3400 may be a quite a bit different from the
2.8 though...  The TCC doesn't worry me too much.. I could always disable
the thing.  I drove like that for a while and fuel economy was for all
practical purposes unchanged.
