[98gm1500]

hey guys, new to the fairly new to the chevy game, doing a tuneup on the truck and was wondering what guys are recommending for spark plug gap on a 98 vortec 350? ngk plugs going in it if it matters, appreciate the help!

I know it's .035" for my tbi. I don't know if the vortecs are different.

i thought the sticker under the hood said .035 but i honestly can't remember, i may be wrong, wasn't sure if people differed from stock either with better results?

Cole tried .045" and said his truck ran like crap.

Vortecs are .060" because they have a better ignition system.

Tbi an older carb motors are .035"
