4176mack Posted February 27, 2013 Share Posted February 27, 2013 Hi folks.Does this look like an engine i.d number to you ?, 5393 P3915 1211 then 64856 stamped seperatley underneath the main line of numbers, it is stamped and is not a part of the casting like the casting numbers are, and is on a smooth machined surface section of the engine block on the right hand side just behind the compressor on my 1979 F786 which has a maxidyne. Opinions would be welcomed. Quote Link to comment https://www.bigmacktrucks.com/topic/30222-is-this-an-engine-id-number/ Share on other sites More sharing options...

Look on the back of the block below the head, on cabovers they were stamped in the back.
