Brian,
Yes the Autolite are plug of choice for stock and aftermarket ignition
systems. For the distributor cap and rotor, go with Borg Warner Select Cap
and BW Select Rotor; the BW Select cap has good brass terminals. I have MSD
8.5MM Super Conductor wires, PN#32189, and simply love them. Very thick and
they hold up great. They ran me about $60 from Summit. If you can afford
them, get them you will also be impressed. You might wanted to also use a
can of Throttle Body cleaner, yes I did say an entire can. I use Gumout's TB
Cleaner, which is designed for the whole can to be used for a good thorough
TB cleaning. I think it runs about $4 for the can, and will help will idle
and overall performance. I use a can every tune up, which is about every
7-10,000 miles since I am running am complete aftermarket ignition system.
Also, be sure to use plenty of dielectric grease o nthe spark plug terminals
and the dist. cap terminals when doing a tune up. Good Luck!
