That's a definite YES to balancing the engine. Especially if
you're bringing in a foreign flywheel and pressure plate.
Done a couple of Model A engines. Originally these engines were
all dynamically balanced by Ford with the crank, flywheel and
pressure plate attached together as a balance unit. I can
confirm that something as simple as turning a flywheel 180
degrees afterwards (which is possible on the Model A) can make a
big difference in how much vibration the engine creates.
Of course to mark things as they come apart is only good mechanic
practice. After components have been reworked I usually do
dynamic balance with crank front pulley, crank, flywheel,
pressure plate together and in their original orientations but
without the clutch disk in place (clutch disk position is a bit
more variable than the rest of the components IMHO)
On the last engine, the balancer asked about doing the crank and
flywheel separately. I replied yes as long as they are done
together afterwards. He didn't like the thought and didn't see
the need but did as I requested. (for additional $ of course)
Best running engine yet.
Good luck,
