Might want to pull your valve covers and make sure that you don't have a cam lobe going flat. By pulling of the coil wire you can crank the engine and watch each valve go up and down to eliminate that possibility. I think it is hard to do a compression test on a 440 with headers, a compression test would be best. Good luck with it.

Bosch and any platinum plug is a bandaid unless the system was designed to run them. "The only thing to do for triumph of evil is for good men to do nothing" "NUNQUAM NON PARATUS!"

Oh, stock electronic ignition. Your best off sticking with Autolites using the stock electronic ignition I myself run Bosch Platinum single or double eletrode on my cars, but they are Petronix equipped

For the newer cars where spark plug changes are 60,000 miles or more I have been using the Autolite Double Platnum plugs. I never really compared different brands of double platnum plugs, so I'm not sure of whos brand is good or bad?

Old Mopars- all my Chargers, Trucks and current 5th ave- standard copper Champions as called for by the service manual. Newer Mopars- my SRT, Caliber, Stratus- same as above. But I did use Champion Platinum in the SRT and Caliber. Stratus has the good ol' copper ones. CC.

Use NGK they are worlds better, I'm sure.
