- Crankshaft End Play: Excessive crankshaft end play suggests wear and potential damage to the bearings.
How Much Does an AMC 401 Engine Cost?
The price of an AMC 401 engine for sale varies significantly depending on its condition, completeness, and the seller. A complete, well-maintained engine will command a higher price than one requiring significant restoration. Expect to pay anywhere from a few hundred dollars for a project engine needing substantial work to several thousand for a fully rebuilt or exceptionally well-preserved unit.
