jeffbyrne Posted November 1, 2010 Share Posted November 1, 2010 The #'s in your pis are cast into the parts, every casting will have those same #'s. what you are looking for is #'s that have been stamped in with a stamp and hammer or similar. Look where fjh suggested, ahead of the fuel pump on the top flat deck of the timing case. Jeff.

peterj Posted November 1, 2010 Share Posted November 1, 2010 If the engine came from a COE, the model/sn number could be on the back of the block,just below the head..

Mike Posted November 1, 2010 Share Posted November 1, 2010 Is this the engine model number (first pic) and serial number? Any engine details jump out? If your engine is an inline 6 cylinder 673 c.i. fuel injected then, the engine numbers are on the front gear cover,passenger side,on top, just under the secondary fuel filter. By the looks of your clean engine, it should be no problem finding it. The first photo is your oil cooler with it's numbers raised or embossed,which most parts are that way. The engine numbers will be etched down inside the housing, same as your frame number and rear carrier housing.

jeffbyrne Posted November 2, 2010 Share Posted November 2, 2010 In the early/mid 70's, the engine designations changed from ENDT675 to T675, or TB675 if fitted with Dynatard.

HK Trucking Posted November 2, 2010 Share Posted November 2, 2010 That engine is roughly a 1972 or newer, because it has the newer style thermostat housing and spin on water filter.
