Hello. I have a 88 rw with a Mack e6 350 that is equipped with the Robert Bosch pump. Truck runs about as good as it should for a 350. The truck is not an everyday runner.  Have done some miner pump tweeks Based off of what the Cummins  5.9l tweeks. .  I was wandering if anyone has any experience with grinding the fuel plate.  if anyone had experience or tips doing it on a e6?  
 

thanks. 

I tried one on a e7454 didn't see much difference. Your better off going straight for hard parts like sending the pump out to flow more fuel and haveing the injectors honed. You wouldn't want to forget about a turbo also. Then find someone to tune it for the extra fuel. All depends how much more hp your looking for out of it.

All I have is a r model tractor. It does need some finishing. Pm me for pics. Thanks.

Sorry it's gone.

wow that is a very sharp truck.. if my superliner had a heavy front axle i would put big front tires on it in a heartbeat.. thats a nice mack lots of horsepower what more could you ask for...

i had a exhaust box my dodge ram cummins that made years back with dual stacks and the sound was just right even cut some of the drone out..

wow!! thatll get you over the hill.. you got any pictures of this beast?

I believe the clutch and pressure plate play a big role. The one Superliner I bought that was doing some stock class pulling has a 4000lb BL plate and clutch in it and there was a spare in the side box!

it takes some serious push to engage the clutch. Owner told me he started in 7th with the mack 18spd.

true.. but it also depends what kind of horsepower your pushing... the more horserpower the heavier plate load you need to hold everything from slipping.. he must be cranking and doing alot of slipping off the line to get it going in 7th gear...how much horsepower was it runing?

what shape are the doors in.

how much hole truck have title thanks jerry

doors arent too bad little rust on the bottoms.

i do have a title for the truck. looking to get $4000 for the whole truck. thanks

That's a nice old r700. What's top speed with that truck? What gear do you think you'll try with the six speed?

Superdog. What kind of rig will you be running? Have hooked to a sled already?

What if I were to leave the engine alone? Should be ok considering the truck used to haul d8s and d9s. I wouldn't think a 10 sec pull on a sled would be all that bad on the engine could it?

Thanks.

Yes itwas a former Connelly truck. Good eye!!

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?

Here's a pic of a model I built some years back. It's the same paintjob. Planning to paint my R611 this way......someday.

I like that color combo. I think goin yellow and black on the frame and hubs would take it one step further.

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. Just my 2 cent

Was your uncles 400hp r 700 reliable being pushed that far?

This truck has the same fenders.

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.

Thanks.it is triple frame The rails are in perfect condition. The fenders are also in real nice condition. Just the cab has taken a beaten from the weather. I'd like to see a pic of the bumble bee if ya had one sounds like a cool truck.

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?

Got around to snaping a picture to share. Gonna start fixin her up as soon as the weather breaks.

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..

I got around to looking for the model number. It's a dm895sx1542. It's a 73. What do you guys think? 325 or 375. Thanks.

Here is a pic of a 375 in a resto that Matt Pfhal did.

Wow that's a neat looking project.!!

Yes I was able to open the link. I'll take a look on the truck and update tomarrow. Thanks.

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.
