plugs for a '69 440

[4eyedblonde]

Are the E3 or iridium plugs worth it in the old 440's? What is the correct plug for these engines?

I just read the answer to your question in the June 2013 edition of Mopar Action. Read Plugged In on page 93.

Cheers

I used Autolite 74's on my old 906 headed 440. Ron
