Im running a 75 shot and im tryn to figure out the best plugs and gap setup to run as safely as possible. I heard Autolite 103 is the best way to go gapped at 0.35 is that correct? Also when ever i go to buy these plugs from a parts store they say they dont have them for my car and they wouldnt screw in WTF..are they just idiots?

i say go NGK, and if you are unsure about gapping, you can call NGK's tech line and tell them your mods and what you are doing and they can give you exact gapping recommendations

They should have Autolites 103's for your car. If not you can get the NGK's also. Gap them between 35-38 if you do not have an MSD box and you will be fine.
