Elliott wroteGet yourself a quality timing gear set and have the motor balanced. Use a new gear on the distributor. Sounds like you've done your research... inspect that Summit cam good if you are going to use it (make sure the oil holes match what things look like on your old cam). Crane also sells a zinc phosphate oil additive to help the molly lube mimimize heat on the cam lobes.
If you go to Bulltears main page http://www.bulltear.com/ (and click on Jen) you'll see they sell AMC specific oil as well - good for these hi-nickle blocks of ours!!
