Yup, what 2002BLGT said. A gap as small as .035 is for when you're running nitrous..

0.045 gap is probably for carbureted cars.....because thats what I'm supposed to gap my plugs to.

For carbs and the '86 EFI.

87 up is 0.052-0.056"

If I remeber right .045 is also the gap for the plugs on my '93 4-popper. He may have just been looking at the wrong engine size on the screen. Make sure he didn't sell you the wrong plugs too. Should be autolite 25's
