I run a rebuilt (NAPA) stocker. Caution :rant:The dist has what, 3 jobs? Signal the ECM, signal the tach and put the rotor in the right place. The rotor is mostly our job...:rotf: What it might look like is immaterial. Now what I can tell you is that the rotor and the cap are slightly out-of-phase. Just look at where the rotor is burnt and where the cap terminals are burnt. I modified a rotor to compensate. It was awhile back, I'll see if I can find some pics. (I would be interesting to see if an MSD dist fixes that.) Everyone seems to think that these motors are hard on caps and rotors. I respectfully disagree. My goofy rotor is 2 years old and the cap is at least one year old. And the truck is raced almost every week. In my experience its the dang wires. When I bought the Magnacor's awhile back I could tell the difference the moment it started. I haven't yet quite figured out how to keep the wires for cyl 2&4 fully protected. I have some new sleeve material I'm gonna try next.
So IMHO go with a stocker, save the money, and buy good wires.
Here's a pic of my modified rotor. Notice where the burnt area is.

It may not make any difference but at least I feel better...:rotf:

Hey Don, what exactly did you modify on your Rotor? What's the benefit?
Thanks
I wouldn't mind to do that but where can i get the correct parts i need?My 1st choice is to rebuild the stock one using ac delco components.
