Best spark plugs for a slant 6 225 - 07/12/10 01:50 AM
I have a '64 Belvedere with a 225 slant 6. I am slowly upgrading to a electronic ignition. What are the best kind of spark plugs to run. I have msd blaster 2 coil and msd 8.5 wires. Putting in a msd 6a next. Anyone have any thoughts or what are you running.
