Would anybody happen to know which of these intake bolts are correct for a 69 383?
Yupper, I agree, no washers on any of mine. Anyone I had though were a few years old but still had the factory intake on them, so I can’t see anyone just changing bolts. KimI would say none of the above. Others will hopefully chime in. I believe they do not have a washer. Would be black oxide. 6 point head. Unsure if it had the "Highland" marking or a TR marking .
U r correct. KimI will say the end that goes into the intake is sorta tapered at that end, not traded all the way down, that helps get them started. Everyone knew that though.
