Im putting together a 306 for my car and just wondering what rings and bearings i should run. Ill probly go with Clevite (sp?) 77 bearings. But im unsure on the rings. Car will be a 10:1 compression motor with h/c/i that will see quite a few street miles, and quite a few trips to the track. Also plan to run alittle nitrous after i get a few miles on it.
