What would be a good spark plug to put into my '73 stock 340? I have been using copper non-resistor champions forever. I get alot of ignition static on my radio. It's also time for new wires because mine are like ancient. I'm considering the champion platinum power spark plug #3405 for $3 each. Anyone else using these?
I'm lucky to drive 500 miles per year, so these plugs will outlast me. I'm not looking for anything fancy, I only cruise on the weekends and ocassionaly open up the back barrels. I'm looking for a quality plug at a reasonable price.
