New Windsor engine?

[PKRWUD]

I should probably clarify.

A short block is the engine block, and all it's internals. What isn't included is the oil pan, and everything from the heads up, including the intake, valve covers, carb, ignition, etc.

A long block is the same as a short block, but also includes the heads.

A complete engine is usually the same as a long block, but also includes the intake, valve covers and oil pan.

Since it's your block and a piston that are damaged, buying a rebuilt short block would probably be your best bet, provided your heads aren't damaged. If they are, then a long block would be best. Either way, the parts that aren't included could be transferred from your old engine. You would only need to buy gaskets and fluids.

Take care,
