AMC 4.0L inline 6 cylinder Engine from 2003 Jeep Wrangler Rubicon. Runs beautiful even after 155,000 miles. Replacing with a Golen Stroker Crate Engine 4.6L 270 H.P. This engine is still installed in the Jeep so you would nothave to take my work for it that it runs great. You can see for yourself. The new engine will be installed in the middle of March so this engine will be available around that time. If you are restoring a TJ and need a great off road engine this is a terrific bargain.
