What if anything do any of you add to older engines designed to run on leaded gas. I know the new oils and unleadded gas don't have all of the additives the older engines needed for proper operation. (Lead, Zinc, and who knows what else was removed)
I have a 1970 sbc 350 with 10.25:1 compression and a 4bbl carb that was 300HP stock. I have not changed anything internally in the engine. Do I need to worry about it?
Thanks for your comments! :blowtiedb: :flag6:
