Marlin is correct- the flywheel can be so marked. This was quitea popular mod in the '80s. Be clever about it & mark the flywheel for TDC & advance for cylinder #4 at the rear of the engine so its more convenient to hook up your timing light. Sadly, once you do get the timing checked via flywheel, you'll still have to access the front of the engine to release the distributor clamp bolt & turn the distributor body for adjustments.
