Think the Ignition module went in my 89 today so have been looking for replacements, anyone got feedback on msd 6al 6420, either good or bad. Also looking at replacing the full distributor since it is now 17 years old, was looking at a GM stock replacement or a D.U.I. direct replacement. Any good/bad comments on these?
Car can now turn to 6500rpm easily so want a good replacement that delivers good spark at high rpm. Was leaning towards the DUI as it had a better module and coil, but need some feedback to convince me of which route to take.
