I noticed from your picks that you reinstalled the TFI distributor, will this cause an issue since a signal is no longer coming from the TPS to tell the computer to advance or retard the timing? I plan on using a vacuum advance distributor (duraspark II) to avoid any electronic issues caused by retaining the EEC-IV ignition components.

TPS-huh? Oh, right. Nothing wrong with TFI, but I guess the main issue with a non-Duraspark distributor is the lack of any sort of mechanical advance provisions .... so no dynamic advance unless, as you point out, the computey doohickey dials some in electrically. So you're basically running with the timing locked out, i.e. initial timing = total timing. I've read that some people actually prefer locked-out timing. Don't remember exactly what was said offhand, but I think part of the motivation was that it simplifies tuning because there's no timing curve to worry about - just set the appropriate total timing and go.



Re the flooding, I imagine Edelbrock would say that's all but guaranteed to happen with the fuel pressure at 15 psi. I second the question of making sure of exactly which bypass regulator you're using - very important that it's designed to function correctly at about 5 psi.
