what plugs and gap

[therover87]

i have an 87 k5 350 tbi and i am going to be doing a tune up soon and i was wondering what plugs and gap i should be using, the motor i stock except for exhaust, thanks.


I would rather push a chevy than drive a ford

I run Champion Truck plugs with .057 gap. But I have MSD ignition. I also run a stage hotter on heat. My dads trucks all run Champion Truck plugs with the factory gap and factory heat. They have worked well for me.

My choice would be Champion Truck plugs with stock, or maybe .01-.03 more than stock gap.

My part number that I run is Champion Truck plugs #4018. Incidentally they are the exact same plug that my dads 92 F350 runs.

My Chevy isn't broken, its just out of gas.
