Hey guys,
There are downloadable PCM manuals in the reference section of the site. They are loaded with info on your engines and tranny. I've read mine from cover to cover and you'll amazed at the little things you can pickup.I rebuilt my 351 with info and specs entirely from these manuals, I think it's good reading and would probably answer a lot of questions in maintaining a properly running rig. Enjoy

Yes, .035 is correct. The Autolite 24's a got for mine were almost dead on out of the box.

Does this gapping go for a 1976 302? Thanks for your help

Just replaced mine, the plugs I pulled were at .045! I called SkiDim just to double check the .035. I haven't dropped her in yet, but after starting her up with the fake a lake over the wknd she sure did sound like she idling quite a bit smoother. Just need to finish up my teak platform and we are good to go!

Found .035 in the engine manual posted in the reference section, so I guess that's the answer. Should I expect to see a difference in anything since previous plugs were gapped at .030? Thanks

What engine do you have? Year? CID? Ford or Chevy? Need some additional info.

Changing plugs for the first time. The plugs that I've pulled have a 30 gap. I do not have the original manual, but from the information that I've read here, I had set the gap to 34. Can anyone verify this? Thanks!
