Colder plug for GT-40P's???

Badstang_88 · 08-20-2001, 12:54 PM

I have been using Autolite 764's for a while in the P's. I have added a 150 shot of N2O and would like to run a colder plug, but none of the parts houses around here can find a plug that is colder than the 764's.

Does anyone know the part # of any copper plug that is colder than the 764's???

Thanks a lot for any help!

I too have the P-heads and I want to throw an new set of plugs in it. I don't run N2O, but would like to know what spark-plug I should be running and what it should be gapped at. Anyone know???

Autolite 103's are one range colder, so are the Motorcraft AWSF22C. Both fit the P head.
