I have all the parts neede to install the Duraspark system.... Maybe.... I got a used distributor but it is corroded and difficult to take apart so I can clean and lube it. So I've been looking at maybe getting a new one in case I ruin it from Summitt Racing but there are too many choices. Such as dual or single vacuum advance, computer controlled or mechanical, modified or not. The engine is not running to it's potential. It has a constant intermittant miss and pings terrible when it is warmed up.          BTW, The coil is getting 12 volts to it.

"intermittent miss and pinging" prolly won't be solved with coil/distrib swap....completely.
Replace those wires.....modify distrib with lighter advance springs and LIMIT the total advance to 36*@ 2000 RPM.
You will need a timing tape too. AND premium fuel.

I got the the Duraspark system installed and running. I had originally bought a used distributor off e-bay but it was corroded and I couldn't get it apart to clean it up and lube it up. So I bought a new one. I tried to get the Cardone unit but they aren't available any more so I ended up with a Spectrum. But what a difference in the way it runs now. WOW. It idles a lot smoother. The miss that it had is gone. It still pings but just for a second when flooring it before it down shifts. I was also able to move the timing from 6º ATDC to 6º BTDC. That's the factory spec before I did the vanilla job (he, he). I'll mess with recurving it later as I don't know what the compression ratio is and guess it will be a trial and error process. I need to get educated on what I am looking for and how to go about it.

I gotta say... you're safer running the pink wire.  You risk burning up the module using 12v straight to the coil.  Of course, the bashes aren't as fun without a breakdown or two.
