electronic ignition upgrade 1987 4.3 v6

Am thinking of changing out the old ignition system with electronic ignition. Any one who has done this.......are the rewards worth the time and effort?

There are a couple of options, but points are not a bad system if you know how to maintain them, I still have points in my '88 4.3 V6.
You can:
convert the points to a Petronix system, this keeps the original distributor but just replaces the points with an electronic triggering system
replace the whole distributor with the GM/Delco Marine EST unit

however, in both cases you will have to replace the ESA module in the Cobra shift system with one that will work with an electronic distributor, the original one will not.

I have found that the points last me about 5 years or so, I replace them when they start to look pitted.
