My SPARK PLUGS keep burning out on me after a quick drive.
I have a 1970 Nova. It has a 355 sbc with factory HEI setup. I have LT1 heads (Aluminum), 10.2:1 pistons, 1.6 rockers, shorty headers, ZZ4 cam,
holley contender intake, 750 double pumper.nks
I had a set of NGK type r spark plugs and they burned up, and engine would not start.
I replaced the spark plugs agian with a set of AC Delco plugs for a 1993 camaro, and it started on a dime but after going around block once, they did not work again like the first couple of start ups. I can start car but only if I crank it for a long time.
what kind of plugs do I get? Can the spark plug wires cause this?
