Hi,
I am putting together the parts to convert over from the ESA/Lean Burn ignition system to the older, mechanical/vacuum advance style ignition. I have one old style electronic distributor, which I may end up rebuilding, or just go with a new A-1 Cardone equivalent, and not have to rebuild anything. The part that I don't know much about is the ignition boxes (some people call ECUs) that Mopar used. I know they came in different colours, which I think are significant, and the chrome box from Mopar Performance.
1. Is there a preferred ignition box? This would be for a street driven car, probably never go over 6000 RPM. Is there any advantage to the Mopar Performance for a street driven car (i.e. is it better at all rpm, or is it basically better after 4-5-6,000 rpm)? The local wreckers have a number of donor vehicles with the Mopar boxes, but are they worth getting, or would I be getting a part that should be replaced anyway?
2. Is a third party ignition box preferred? By this I mean an MSD 6 family, MSD Streetfire, or a Pertronix Ignitor (if so, which Ignitor module, I, II, or III)?
As for the distributor that I have, the shaft (trying to wiggle it from the slotted end) has no real side to side play, but does have some vertical play. Is this important, and if so, do I just add washers between the plastic collar on the shaft and the end of the distributor body, or do I need to try and find the official Mopar upgrade kit for the plastic collar (the one that has the added perpendicular collar)?
