richard-b61 Posted June 15, 2015 Share Posted June 15, 2015 Before I start searching the thru the dirt on the engine of my B61 for the engine info, is there an information stamp or plate some place on it that tells weather it's an END-673 P, C? All I know is that it's an END-673 non-turbo. Quote Link to comment https://www.bigmacktrucks.com/topic/40485-end673-engine-information/ Share on other sites More sharing options...
Freightrain Posted June 15, 2015 Share Posted June 15, 2015 The accessory drive(lower passenger side), on the top of the casting at the front of the motor will be END673-(and then engine code). Might take a flashlight to actually see it(or clean off the crud). About 3/8" tall stamped letters.Does it have a split intake manifold? or one piece?
