so new points and cond are "ok................ the 318 I am talking about used to burn them up quikly. ............... Or bad coil?................. I probably had them way wrong as far as adjusting. ................
I took the context to mean that if you had a properly working ignition, whether points, Mopar breakerless, or maybe Pertronix, that if you spent a lot more on an MSD, that it isn't worth the money.
The advantage in breakerless over points is that obviously the points don't wear, so generally more reliability.
The primary reasons points burn is
1--certainly bad, or more likely wrong coil
2--wrong coil resistor, or bypassed, or bad condenser. Condensers (capacitors) are not just "good or bad," and neither are coils. Condensers can have reduced capacity, which causes points wear, can be leaky which causes poor spark, etc.
3--Set incorrectly. If points are set too close, or you don't lube the rubbing block and THEN they wear towards closed, this also causes burning
The single points Mopar distributors seemed to also have more problems relating to the advance plate/ breaker plate. The vacuum advance changes points dwell, and that indirectly affects timing. With a little wear in the parts of the distributor, the usual result was an over--advanced condition
The last problem is not something that commonly shows up in typical old-school GM V8 design distributors, although GM inline 6 dist's were nothing to brag about, LOL
