When the teeth sheared off the T-belt, only the crank continued turning. The camshaft and intermediate shaft stopped.

Actually is it pretty easy to re-time the engine.

The cam drive gear has an indentation on it, like a punch mark. Line it up with the mark on the piece behind the gear. Use something like "Wite-Out" or "Liquid Paper" to mark those places.

Similar deal on the intermediate gear. Indentation on the gear, mark on the piece behind it. That one I have practically never seen. So I remove the distributor cap (it's a 240) and see that the rotor points to a mark on the upper edge of the housing. If the rear of the car is 12 0'clock, the mark is about at 7 0'clock. With that in place yo will be looking the right place opn the inter. drive and mark. Use wite out here, too.

The mark on for the crank is a little trickier. I have worked on B23 and B230 engines, and my recollection is mixed between them. Amother brickster will answer better than can I.

If the timing is not right when you try the engine, you have added labor to the job but have done no damage.

Good luck,

Bob
