tl1975 Posted January 30, 2022 Share Posted January 30, 2022 Any idea what engine is shown in these two pictures? Endt-673 or endt-675?? No info tag behind the fuel lines. It’s in a friends 69 R model. Quote Link to comment https://www.bigmacktrucks.com/topic/69127-what-engine/ Share on other sites More sharing options...
63BMack Posted January 30, 2022 Share Posted January 30, 2022 Take a wire brush to the top of the block right in front of the 2 bolts on the fuel pump it will probably have ENDT675 stamped in the engine block. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69127-what-engine/#findComment-488207 Share on other sites More sharing options...
terry Posted January 30, 2022 Share Posted January 30, 2022 would have to say it isn't a T675, looks like no oil cooler there on the left side. terry Quote Link to comment https://www.bigmacktrucks.com/topic/69127-what-engine/#findComment-488209 Share on other sites More sharing options...

doubleclutchinweasel Posted February 9, 2022 Share Posted February 9, 2022 Look for numbers stamped anywhere around here. Usually had something like "T 673 C". LOOKS more like an ENDT-673 or ENDT-673C. But, I BELIEVE some of the earliest 675's may have had that cartridge-type "oil clarifier" instead of the spin-on filters. Like they said, VIN number will give a clue as to the original engine. Best place to get the VIN is actually on the RH frame rail, just behind the front shock mount...just barely out of view in your picture.

doubleclutchinweasel Posted February 9, 2022 Share Posted February 9, 2022 Look carefully, and you can see the stamping on my old '70.

doubleclutchinweasel Posted February 9, 2022 Share Posted February 9, 2022 VIN number on the frame will look something like this. Again, behind RF tire, ahead of the cab. VIN number plate in the door may or may not match! Quote "Eagles may soar, but weasels don't get sucked into jet engines."
