i was wondering what type of spark plugs and gapping would be best for my 87 5.0 with a few bolt ons such as msd coil, fms 9mm wires, acell cap rotor, h pipe, flowmaster catback, 190lph fuel pump, 19psi injectors, k&n filter, 12* base timing. i have motorcraft now with a 35 gap and i don't think thats set right any imput would be gratefull.. thanks

WOW .035 gap??? Maybe for a S/C car, but thats way to small for a your set up.
Motorcraft plugs work fine, but I still prefer Autolite #24's. Stock gap is .054, so that's where I would gap them to.

No .035 is not right lol, you where correct in that. .035 is way too cold. HiFlow is right.

Either or, I like 24's cause they run a little colder and richer, but 25's are stock.
