Just rebuilt a 327 on my 68 Vette and there is no oil coming up to the
rockers. Any ideas where the clog might be or how to clear it? I
used the tool and drill to prime the oil channels but it won’t flow
anywhere but to the oil pressure port. Is there a diagram of the oil
channels and oil path availabe somewhere?

The oil comes up the pushrods, last place in the engine to get lube, how
long did you prime it for.

What lifters do you have and how did you adjust them?
How long did you run the primer?
You did remember to install all the oil gallery plugs?
Basic oil flow in the small block is
Mains/rods (through the crank)
Camshaft (oil comes up from the mains)
Lifters (through the oil galleries on either side)
Rocker arms and valve stems
Drain back into sump from all the above (drain from front camshaft
bearing lubes timing chain)
Hey gshafer, pay close attention to Steve W's list above--I'd guess you
oughta look closely at one particular area I've seen problems in
lately--Steve's "Filter/bypass" reminder! Somehow those early 327 year
engines cause basic misunderstanding of what goes where, and lately I've
seen several so-called "factory-rebuilt" engines with parts omitted. s
