Good reading..thanks Tom

Good stuff, especially the " Ignition Anachronism" section! Non-resistor plugs for an MSD.News to me. Guess the F"R"3LS arent the top choice!

427L88, I went back and looked at my MSD book and it said nothing about what plug to use, it just said test and tune. It does say run a resistor wire. Could this be something that has come up in the last few years, my book is about 5 years old.

Ck out autolite site also, under tech docs.. Here's a link:
