Well, I have finally gone over to the "other side" and converted my '71 Z's mechanical point distributor to an electronic type by installing a Pertronix Ingnitor unit.
I did this in order to remedy a loss of power I seem to experience during hard acceleration on the higher end (around 4500RPM). I always knew when I needed to replace the points in the Z when I would notice a stumble under load at low RPM. The Pertronix unit installs easily (as many of you already know). This did seem to help smooth out the overall performance of the engine providing quicker starts, smoother low end and better performance on the high end. I still have some drop in power as it kinda flatens out at over 5500 RPM.
I've read other posts on this site where people have had similar issues which may have been caused by poor fuel, dirty fuel filter or even a poorly performing aftermarket mechanical fuel pump. I have had one of these "stamped metal lid" type aftermarket fuel pumps installed for years now so I figured that maybe this could be limiting fuel flow to the carbs as I believe Frank T may have suggested in an earlier post. Soooo, I ordered and received an OEM style fuel pump which I plan to install tomorrow. Hopefully I can give it a trial run on Tuesday when the weather gets better. I've always put at least 93 octane in the tank so that should not be a problem. The fuel filter is clean and valves are properly adjusted. I may be advancing the timing a little more which seemed to help also. I just don't want to go too far advanced where I then start to get that nasty pinging under load.
Oh!, I'm keeping a spare point set in the car just in case.
More later!
I've done the same thing Frank. I got to the point where I found it was easier to just pull the distributor (after recording the clock position of the rotor of course) and replacing the points and condenser on the bench. That way I could easily rotate the distributor cam to to make full contact with the new point's rubby thing. Replacing the condenser was easier that way also and I usually check the timing after a point install anyway. It was also a lot easier to shake out any screws that fell down into the distributor.
