I probably should keep my mouth shut here because I know almost nothing about the V8’s but i think i read somewhere about there being a 998 cubic inch ENDT-1000 and an ET-1005 that was a predecessor to the E9 in the early superliners. From what i read it was basically like an E9 but with no charge cooler. There was also a maxidyne EM9 i read, and was painted gray. As far as the pictures show the engine is the gray color which seems correct for mid 1980’s? I think maybe they were 4 valve and weren’t the 865-866 engines 2 valve? . The factory color for the 865 was gold as it was a maxidyne. I believe the 866 was painted more of a silver as it was the thermodyne color. Of course the original engine could have been repainted or swapped out or both. im just floating the possibility of it being the ET-1005 or EM9 and is original? I certainly don’t know. Someone with more knowledge than me will surely be along. Im curious. Its a cool old truck Josh.

Someone that knows more than me will be along soon and clarify but 1550 rpm does not sound right to me. My understanding was that even the “L” engines were governed at 1800? And i may get flamed but where I live Johnny law doesn’t pay attention to smoke so id ditch the puff limiter especially for field work. Im sorry your having so much trouble. I understand the frustration as ive been fighting with an N-14 all winter that’s still not right. Sometimes things seem to never want to line out. Lol. Good luck Josh.

Oh man that sucks im sorry about that. Hopefully you are good to go now. josh

Well do you know how she pulls yet?

These are 6 spoke front and back and all of these trucks were 11R-22.5 rear and 385-65-22.5 fronts. The drop axles all have low pro 22.5 Josh

Ill have to get by there and look it over again

Thank you. This is a potential mostly complete parts truck that has been offered if a price is agreed on and im trying to figure out how much of it is actually useful to me. I appreciate you guys help Josh

Yeah Joe it was built new as a mixer which im sure explains why it’s a solid walking beam. I just don’t know how to tell what the rear axles are by looking. It has the bolt on caps over the trunion where my 38’s are open ended bushings. So 44 seems plausible. I sorta expected that they would be heavier than 38 being a mixer but I wouldn’t really know. Do you know if any of it will interchange with my 38 camelbacks? Mine has 4.17 will they work in the heavier rears ? Bolt in? Or are they different? I think the 5.73 in the mixer rears are too slow for my use. Might help my power though. Thank you for all the replies btw. Josh

I called mack. They cant tell me the rear suspension. Only the numbers on the tag that I already posted. The guy was surprised to hear they could be 38’s in a mixer. He said he hadn’t heard of that. He said that the front axle number is FA617C but couldn’t tell me anything else. He said their data is pretty limited these days. josh

Gotcha. Very well could be I suppose. I assumed since it was built new as a 12 yard mixer it would have heavier rated axles. But I don’t know that to be sure. It has 5.73 ratio. josh

With the 6 spoke hubs ? We had some around when I was young that were 5 spoke. Josh

Anyone ever know what rears these are? I know they are a solid walking beam but are they 44’s? Or 58’s or what? josh

Yeah im sure the 3406 is too long. I have a big cam here and I’ve tape measured around on it and it’s definitely too long. Only real option im seeing then is the mack E6-E7 of course and then possibly a C-12 which i dont have and don’t want to mess with the electronics and something like a 671 or 6v92 and being im the driver im not listening to that. Lol. Im still keeping an eye out for a mechanical E7 or vmac i cant put my robert bosch pump on. Sounds like the 3408 is too big to fit but from what I read the 3408 is wayyy heavy as well. josh

Well there ain’t no stuffing one in a R600 then! Lol

I dont know what else would fit besides E6 and E7. Saw pictures of a C-12 in one. Im sure some version of the old Detroit 2 stroke would fit but i have no interest in a Detroit. Lol. I figured someone on here has seen or done something unconventional. Lol josh
