Superdog Posted March 22, 2014 Share Posted March 22, 2014 chances are pretty good if it's a '73,it would be a ENDT673C 250 hp. Have him look at the trucks VIN number,it should be a letter or letters depending on what it is,R,CF or MB,the next 3 numbers should be 611.

Deere Mack Posted March 22, 2014 Share Posted March 22, 2014 just talked to a guy 150 miles from me that is scraping out a 73 mack fire truck with a 6cyl. thermodyne it has 82,000 original miles on it and he wants it sold but he can,t find the id tag. any help experts?The truck I just bought has an engine from a '73 fire truck or at least thats what I was told. The engine date is '73 and the number is ENDT 675. No matter what it is I'd say its a good find!

Superdog Posted March 22, 2014 Share Posted March 22, 2014 The ENDT675 is a Maxidyne,so it would have been out of a CF,R,or MB 685 fire truck. Quote Link to comment https://www.bigmacktrucks.com/topic/35125-thermodyne-engine-size/#findComment-238627 Share on other sites More sharing options...
Maddog13407 Posted March 22, 2014 Share Posted March 22, 2014 endt673c and b engines are about impossible to find now a days. at least save the engine. they weren't as common as a 675, 237 Quote Link to comment https://www.bigmacktrucks.com/topic/35125-thermodyne-engine-size/#findComment-238636 Share on other sites More sharing options...
doubleclutchinweasel Posted March 22, 2014 Share Posted March 22, 2014 Here are a couple of shots of the model and serial numbers on the gear case of an older 6-cylinder.See if you can get these numbers, as they will tell you more than anything else.This one says "T673C..." which makes it an ENDT-673-C.
