I need to know how big of a gap do i need for a 1991 formula firebird 5.7L V8
SOURCE: What is the correct spark plug gap for a 301
I looked under the hood at the factory sticker, (which is still readable) and it said it gaps at 0.60. So, that is what I did and everything turned out fine. And I do not believe in paying or charging anyone for this kind of information.
