It's possible you've got one or more slightly worn intake guides. It will
suck in a bit of oil and, by reducing the effective octane level of the
fuel, cause it to detonate slightly. The next time it happens, check the
mirror, and see if you can see a puff of smoke or two. I had a similar
problem on my 72 some time back, and that's what the culprit turned out
to be.

Have you checked the mounting bolts for the rear shocks? And/or the link
bolt at the spring pad? The sporadic part of the clunking sounds like
something slightly loose. While you're under there, I'd check every
fastener I could get a wrench on, just to be sure.
Good Luck!
