24vman Posted January 11, 2014 Author Share Posted January 11, 2014 Thanks double clutch. The worst part of the truck is the cab but were fixin to swap it with another dm800 cab. Just wish it would of been the 375hp engine. Is there a lot of room in pump adjusting to at least get it to 375hp?

j hancock Posted January 11, 2014 Share Posted January 11, 2014 Interesting to see the Farr air cleaner. May have had better flow for the V8. Quote JimIt doesn't cost anything to pay attention.

doubleclutchinweasel Posted January 11, 2014 Share Posted January 11, 2014 We had a couple of R700's with V8 Maxidynes & 6-speed Maxitorques which had the big square air cleaners on them.My favorite was the yellow/black one (old green dash model). Dual chrome stacks. Chrome mirrors. Chrome fender-mounted mirrors. That truck just glowed. At idle, that big long 700 hood would sort of quiver, causing the light to reflect off of it & kinda "shimmer". The air filter looked right at home on that big long mother!The other'n was solid black (still green dash). It was cool, but never shined like the "bumble-bee" colored one.Never forget those big square filters. Nor the unusual sound of a V8 through the dual stacks. It's different, ain't it!

24vman Posted January 12, 2014 Author Share Posted January 12, 2014 I thought so at first. Then I seen another similar truck on youtube with the same fenders. After see the other truck I'm not sure if somebody else had the same idea or maybe they were and option. Beats me.

Just wish it would of been the 375hp engine. Is there a lot of room in pump adjusting to at least get it to 375hp?Take it from me 325 is much better! My Brother and I have both the 325 and a 375 that are pretty much stock and the 325 has a much better torque rise. My Great Uncle had one years ago in a 71 R700 and he played with it quite a bit and he had well over 400 horse power.

Yoos Brothers Construction Posted January 12, 2014 Share Posted January 12, 2014 He put a million miles on it before he sold it in 1985. Of couse he rebuilt it once and always kept up on replacing bearings when needed and he didn't beat the liveing shit out of it . He respected the power. The problem now a days is finding parts for the 866's. There nearly impossible to find. Luckily my Brother and I have a nice little stash of parts just in case something ever goes wrong with ours. I'm going to have mine set up to be about 425hp in the not to far future because it runs really good but I would really like to make it run closer to what my Great Uncle had his set to.Thanks, Josh Quote Link to comment https://www.bigmacktrucks.com/topic/34181-ednt-866-325hp-or-375hp/page/2/#findComment-226255 Share on other sites More sharing options...
b61mack Posted January 12, 2014 Share Posted January 12, 2014 Did you leave the 5 or 6 speed in the 865 or do you have a multi speed transmission. I was thinking about the older 10 speed Mack, would it work rite with a 325, just wandering.

24vman Posted January 12, 2014 Author Share Posted January 12, 2014 nice.... What kind of plan have you come up with to get the 325 to 425? Injectors and turbo. Or are other ways of unlocking extra power?

Yoos Brothers Construction Posted January 12, 2014 Share Posted January 12, 2014 All I'm going to do is send the pump out and have the pump shop set it up the way I want. Thats all you really need to do to get the horse power your looking for. If you want more than that out of 325 you would need a bigger turbo but it would more wise the replace it with an E9 which is easy to get parts for if. As far as I know they didn't make bigger injectors for the 866 V8s but I don't know for sure. My RS700 has the 375 (it was originally a 325)with the 6 speed and my brother has the 325(originally a 375) with a 12 speed and what a diference there is between the 2. I do have a 1070 Mack 10 speed for mine but I need to overhaul it before I put in. The 10 and 12 speeds work really well with both engines but the 5 and 6 speeds work much better with the 325 than the 375 because of the torque differences and operating ranges as well. In my opinion a 325 with an old Mack 10spd or 12spd is the ultimate set up.

Yoos Brothers Construction Posted January 12, 2014 Share Posted January 12, 2014 You can advance the timing as well but you don't want to advance it very far as they already have quite a bit of timeing to begin with.Josh Quote Link to comment https://www.bigmacktrucks.com/topic/34181-ednt-866-325hp-or-375hp/page/2/#findComment-226297 Share on other sites More sharing options...
b61mack Posted January 13, 2014 Share Posted January 13, 2014 Thanks Josh, I have 3 1070 10 speeds laying around, if and when I get started on my project I was thinking about putting the 10 speed behind my 325.
