24vman Posted January 13, 2014 Author Share Posted January 13, 2014 Yes itwas a former Connelly truck. Good eye!! Quote Link to comment Share on other sites More sharing options...
Joe Ditchkus Posted January 13, 2014 Share Posted January 13, 2014 Jim Conally also had a B-61Sx that is sitting at Highway next to Pilot at Exit 175 on I-81. It must need engine work as the hood and fenders have been of of it a few years.Cab looks good from highway. Joe D. Quote Link to comment Share on other sites More sharing options...
skip Posted January 14, 2014 Share Posted January 14, 2014 You wont be able to buy parts for that engine if it shits itself. If you want 400hp then get an E9. Personally I wouldnt use an 865 for that sort of work.Thats just my opinion. Skip Quote Link to comment Share on other sites More sharing options...
41chevy Posted January 15, 2014 Share Posted January 15, 2014 Not nitpicking but the fenders are wrong. They look homemade.Combs Custom Mfg made fender caps for the the RD800 and 888. I've seen a few put on the DM800 fenders to give the hooded look to them. Horan Sand and Gravel had a few on their DM's in the mid 80's Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment Share on other sites More sharing options...
24vman Posted January 15, 2014 Author Share Posted January 15, 2014 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. Quote Link to comment Share on other sites More sharing options...

24vman Posted January 15, 2014 Author Share Posted January 15, 2014 Superdog. What kind of rig will you be running? Have hooked to a sled already? Quote Link to comment Share on other sites More sharing options...
Superdog Posted January 15, 2014 Share Posted January 15, 2014 Going to try it with this '75 RL795LST. It's got the 325,2 stick 6 speed and 44k rears.Haven't tried pulling yet. Quote Link to comment Share on other sites More sharing options...
24vman Posted January 15, 2014 Author Share Posted January 15, 2014 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? Quote Link to comment Share on other sites More sharing options...
Superdog Posted January 15, 2014 Share Posted January 15, 2014 it's a 65 mph truck, I'm thinking 3rd gear Quote Link to comment Share on other sites More sharing options...
41chevy Posted January 16, 2014 Share Posted January 16, 2014 RD800 fenders are completely different than DM800 fenders. Again, you can have them made any way you want, but they are not correct.They were fender caps, not full fenders. only the top most part and 2 inches on the side. No light panel, hinge point or marker light panel. They were originally 1/3 of the cost of stock fenders. Nothing more than a cheap quick fix to cover up damage. Nothing like a stock style fender though Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment Share on other sites More sharing options...
DM897SX Posted January 16, 2014 Share Posted January 16, 2014 It would be interesting to see a DM800 with fenders like this. Do you have any pictures? Quote Link to comment Share on other sites More sharing options...

DM897SX Posted January 16, 2014 Share Posted January 16, 2014 Thanks. What I was looking for was pictures of Horan's DM800s with RD800 fenders. Quote Link to comment Share on other sites More sharing options...
mackdaddy Posted January 16, 2014 Share Posted January 16, 2014 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. Quote Link to comment Share on other sites More sharing options...

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?

mackdaddy Posted January 16, 2014 Share Posted January 16, 2014 I took it down to the dealer's dyno and it only went to 1150hp and we pegged it with little effort! The E9 is also balanced and spins at 4000rpms..........sounds like a locomotive Quote Link to comment Share on other sites More sharing options...

mackdaddy Posted January 16, 2014 Share Posted January 16, 2014 Here you go......Remember the square baffle that was popular with Detroit guys in the 2 cycle days? this is on the truck and I thought that would be the first thing to go.........but it sounds so damn good I am keeping it. 1 Quote Link to comment Share on other sites More sharing options...
24vman Posted January 16, 2014 Author Share Posted January 16, 2014 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..
