Complete rebuilt engine, L Head, 134 Engine. We believe this is a Willys MB block due to the location of the serial number on the oval pad on the upper passenger side corner of the engine block. This also has the early chain driven camshaft and timing chain. Note: This engine has a very small leak at the rear main seal due to a pitted rear crankshaft. We are selling this engine at a loss due to this small leak. We have over $4,000 in this rebuild.
