Does it only happen when under a load or can you sit there and rev it to hear it? I would try to retard the timing a bit to rule that out as well, just to see... I had lifters act like that as well on a 283, no clatter until a certain RPM, sounded like a rist pin or piston slap. My $.02-

I agree with Herb. If its a stick does the noise go away when you push the
clutch in ? Throwout bearings can make all kind of little noises.

Did you verify that the timing mark on the damper is
accurate? It's not unheard of for the rubber to weaken
and allow the outer ring to slip in relation to the
inner

We took your advise on having the 327 heads rebuilt good
thing to - the original motorhas the power pack heads with small
combustion chambers and the 350 heads had 76cc combustion chambers. We
