340 dual point??

I had Jeff Schlemmer of Advance Distributor rebuild a distributor for me, and asked him, "Would you run a Pertronix, or points?". He said points, so that's what I'm going with. I admit it's a PITA to set the duals when they are way in the back under the hood where you can barely reach them or see them. I usually pull the whole thing out and set them on the bench.
or even better, set 'em up and run that puppy on the machine to get it DOBA and burnish the points at the same time!
