Thank-you. The old plugs came out clean at .045-.050, and the new ones went in at .038. So I guess my timing will be a little reatrded from spec, but that's okay by me as I like to lug my engines: I imagine it gets me fuel economy. I'll let you know about that tomorrow, as I have a 250 mile trip to knock off through the coast mountains, and on the return leg I'll be loaded to around 1000 lbs.
So if I delete the belt-driven fan on installation and use electric fans, will there be clearance?
