Help me understand timing

[jaxter1]

Well, that's the big question.....pushrods with dist's you can turn by hand are out. I'd still go for as extreme advance as practical on a 4.6....I've mentioned it before, but I still wish laptop interfaces like Moto, Autotap, Scantool etc could actually adjust things on the fly. That would be so much better than using a chip....I've yet to see an OBD2 laptop interface that can prog/flash or modify on the fly.
