292 Engine Condition Question

[aotte1]

Starting to disassemble 1965, 292 inline 6 cylinder engine. Purchased engine used. Seller said the engine was from a low mileage ambulance. So far, have the cylinder head off and looking at cylinder walls. The cylinder walls show no signs of ridge wear. Have not looked at all the cylinder walls yet.

Question is do these engines typically have a wear ridge at the top of cylinders where rings stop?

Still evaluating engine, and need to make decision on, to keep as whole engine or save for parts. Original plan was for it to be a parts engine, however, looks to be in good condition so far.

More details later.

thanks,
Les
