DUI says you can gap them at .055 inch using their distributor, due to all that firepower

Keno,
Thanks for the follow up. By standard/performance I meant essentially what you listed. The standard Autolite/Motorcraft/NGK? or The Iridium/Platinum/Golden laced laser cut carbon copper titanium blah blah blah........... load of marketing crap of the week buzz word. I just didn't know if anyone had found a better than most combination. Thanks |

Don't know what your "standard /performance" plug is for the Explorer but in Autolite numbers it is probably an Autolite 104 or 764 and that's the same plug that most people here use in a GT-40p.
If you want to spend money you can go with the AP or APP versions of the same plug. The 104 is a full threaded version of the 764, otherwise it functions the same. They're interchangeable |

Hello,
So I pulled my 351 this winter and had it rebuilt. I followed the recommendations from many of you and went as follows: 351 PCM RH (.30 over) Cam Research Water Ski Cam GT40P Heads (pulled from 97 Explorer refurbished and custom valve job, new springs) Edelbrock Performer Intake Holley Marine Avenger 4 bbl D.U.I Electronic Ignition My question is which spark plug to utilize in the new heads? I can go with the standard/performance plug for the 97 Explorer or mimic what PCM used on the later engines with the GT40P's but wanted to know if any of you have any suggestions/experience????? Thanks |
