53moneypit: your right. It was .125 but hey, its been 44years ago!! I never had a problem with it running hot and that engine lasted almost 2 years...UNTIL my brothers slipped it off to Shady Sied Dragway one day while I was in the hospital. They did run it hot and it cracked #3 cylinder almost the entire length of the bore. For its time it was a hoss. The only problem I had was the rocker studs would work up a little and require re-adjusting ( I had never heard of putting pins in them or screw in studs.....but hey, I was just a kid and didn't know all the other stuff I later learned but it don't mean I didn't enjoy every minute of it.
Nice comments Hotrod Lincoln.
