I have a bone stock 383 2 barrel and I'm not sure which spark plug to go with. she's a cruiser and I don't hot rod her "much". I don't know weather to go with a cool or hotter plug and the geniuses at the parts store can't even tell me which is the hotter or cooler plug, the autolight 85 or 86. I appreciate your input guys. Thanks. Anthony NV
