In amongst my other issues i found that I have two different size spark plugs, larger on the drivers side. I will post pictures of the plugs side by side when the wife brings the camera home. Not sure why the PO did this. JP

Weren't there different size plugs required for some different years of heads? If so, wonder if this motor is running two separate years/styles of heads. |

Different size (diameter) bigger around. Yes they were on the left/drivers side. The guy I bought it from had it for 6yrs and never did anything with it as he has a Moab special. I replaced the ones on the right side and re-gapped the other ones. I will buy replacements when I get a chance. No way it is running as both fuel tanks are lying on the garage floor. JP |

My 68 302 4V head had larger plugs 13/16" than later models 5/8" I used to know this all by heart but have lost memory from many various brands of wobbly pops. more than likely someone changed a head out when another one was broken somewhere down the road. |

That is what I kinda figured, someone along the line replaced a head. I will make it work till I can get the funds together to replaced the engine. JP |

Yep, someone swapped a head. Early plugs were 18mm thread and later plugs were 14mm. The change was sometime mid-70's. |
