Default E3 Spark plugs
Hi everyone, please help settle an argument on my 427 side oiler. I have a 1965 427 side oiler w/428 crank (stroker). Stock cast iron heads w/10-1 comp ratio, ss valves, MSD ignition, crowler cam (16331) 551/565 lift, 2 600 cfm Holley carbs. all set with 24 BTDC timing. Currently I'm running Autolight AP-45 plugs w/.045 gap. I want to try putting E3 spark plugs on to see if there is any noticeable difference. Is there any recommendations from anyone? Also any noticeable difference in your engine performance?
Thanks for your time.
