I just bought a set and gapped them at .050, and the car runs like crap now. It is missing badly.

What gap is everyone running with NA apps and these plugs. I have asked two "experts: around here, one suggested .043, the other .030. I was thinking about going in the middle, maybe ...035ish So....you all are the tie breakers!

Car is all bolt ons possible, plus a big cam.

 

I gapped mine at the factory .050 and everything runs fine.

 

also gapped at .50 runs great

 

I gaped mine ( when I ran them )at .50 with no problems. I don't mean to sound stupid or redundunt but are you sure you have all the plug wires to the right cylinders? Sounds like you have a plug wire backwards which will cause the car to miss. Good luck!

Ya i know they are all on the right cyl. I did the wires 1 at a time to make sure of that.

Guess im gonna go back in and lessen the gap a little, and make sure all the wires are snapped on well.

Thanks

 

Did You have any headwork done? I run mine between .040 and .045

 

I ran mine at .060, but that was with an MSD 6AL and blaster coil

 

No head work, but the cam is a big factor. Its pretty radical and i know it is playing alot with the cyl pressure. 234/242 with lots of lift. Anyways, im using a 6AL box, with a Accel coil.


First things first, ill go under there tomorrow and make sure all the wires are snapped on tightly, and that none of the wires are toasted.

Mine are gapped at .045

 

I don't see any reason you would not want to go with the stock gap.
