Usually, knocking indicates bad bearings on the crankshaft. You are going to have to budget for a rebuild on the bottom end of the engine. If the engine has extreme mileage, you would be better off with a remanufactured engine.
your best bet is to get a used motor or if you have the money then buy a new one but either way they are kind of spendy. the cheapest motor i have found was used and priced at $500
