Hi all! I'm restoring a 1960 D100-108 Sweptside that I've owned since 1975. It originally had the 230 flathead six which bought the farm so I transplanted a 72 Duster LA 318 into it. That served me well for many years but has since also gone to tbat great mopar boneyard in the sky. I'd like to drop a 318 Poly into it this time but I'm concerned about the availability of leaded gas for tbe older heads w/o hardened seats. Can these motors be run on unleaded fuel? What about lead substitutes? Any feedback would be appreciated. Thanks!
