I'm reading your forum question of a knock on cyl #1 as it applies to my situation. I'm just getting my 52 chevy pick up on the road....original 216. I drove it up the road less than a mile and when I put it in 4th and gained some rpms I started to hear a knock. It went away when I slowed and came back again at higher rpms. Should I investigate the same things you guys advised him to check out? Could the dippers be aimed off? Comments?
