24vman Posted January 10, 2014 Share Posted January 10, 2014 I am trying to figure out which v8 I have. The truck is a 74 dm800 tractor. V8 with six spd. I looked on the valve covers but nothing. Is there any other way of finding out? Thanks. Quote Link to comment https://www.bigmacktrucks.com/topic/34181-ednt-866-325hp-or-375hp/ Share on other sites More sharing options...

Superdog Posted January 10, 2014 Share Posted January 10, 2014 the vin # of the truck would start out DM895 if it's the 865,which being it's a six speed its almost gotta be,not saying 100% because you never know what some people do.

Brian Blaylock Posted January 10, 2014 Share Posted January 10, 2014 The serial number for that engine is on the flat surface of the block just above the pan on the pass side it will be stamped either endt 865 or 866 then the rest of the number Quote Link to comment https://www.bigmacktrucks.com/topic/34181-ednt-866-325hp-or-375hp/#findComment-225749 Share on other sites More sharing options...
BAD DOG Posted January 10, 2014 Share Posted January 10, 2014 866 was 375hp and was silver in colour. Usually came standard with Mack 12spd or Fuller 15spd. 865 was 325 hp and gold in colour and came with Mack 5 or 6 spd. It's hard to say what you have there because who knows what someone has done with the truck over time .

doubleclutchinweasel Posted January 10, 2014 Share Posted January 10, 2014 Like the man said, the model number will tell you what engine the truck came with. And, the ID number on the engine is pretty much foolproof.I've got all the model number vs. engine number stuff around here somewhere. I just can't seem to remember where it is.IF I RECALL CORRECTLY, 864 was non-turbo (as in END-864). 865 was single turbo Maxidyne. Wasn't the 866 dual turbo??? Maybe not...Sorry if I'm incorrect. The drugs are still messin' with the Weasel!A couple of images to ponder (hope they are legible)... 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

mackdaddy Posted January 10, 2014 Share Posted January 10, 2014 TheENDT 864 option was a dual turbo engine with 255-350hp depending on set up. Of the few hundred produced most were the 255hp.

24vman Posted January 11, 2014 Author Share Posted January 11, 2014 Bummer i was hoping it was the 375hp engine.. but anyway i plan to sledpull with the truck alittle. my question now is, is there alot of adjusting that can be done on the pump? maybe a little timing. id likie to get it to 400 425hp with not alot of hard parts, and maybe put on a smoke show. but this is just for fun not looking to be a sledpulling champ. thanks for the info so far..

Thanks.And let's do the obligatory pointing out of the "S" for tandem (all DM trucks were tandem, I believe), and "X" for heavy spec...just in case any newcomers are wondering...Glad these guys were able to help you out with the identification.

doubleclutchinweasel Posted January 11, 2014 Share Posted January 11, 2014 Not all DMs were tandems.Really? I've never seen a single-screw DM!
