need spark plug gap help

[dustoff440]

Ngk zfr5f-11 plugs in a 360 Magnum bone stock except a knock off air gap with a 650 double pumper and a cam 112 cl /498 int and 512 ex , MP Dizzy with msd6al, I have no idea what the gap should be on the plugs.......

.035-.040 . i like .035 myself

 

[toolmanmike]

I agree. .035 As the plugs wear the gap will open up anyway and a few thousands gap won't make much difference.

Ngk zfr5f-11 plugs? :banghead: theres the problem there... but anyway gap them at 0.035

I use what MA mopar used for plugs champion RN12YC gapped at the factory 0.035, or in magnum engine cases I believe there RC12YC (smaller socket size)

I didn't just choose these off the shelf, check this on plug selection...

Kenne Bell company says they did extensive research and testing on their
in-house DynoJet 148C, and recommend the "V" design NGK ZFR5F11 (stock number
2262, resistor inside 4,000 ohms) for non-supercharged,
and ZFR6F11 (one heat range cooler) for blown 5.2/5.9 Dodges.
