Popular Post LocomotiveBreath Posted August 18, 2019 Popular Post Share Posted August 18, 2019 Hey guys it’s been a awhile since I’ve posted anything but I’m finally a proud Mack owner again. I just bought this ‘78 RWS786LST Superliner. It’s a long term restoration project that runs well. I’m trying to figure out how many ‘78s were built and what is the HP rating on the engine which I believe to be original. It is a Gold Dog truck and the VIN plate says Mack Western which I have never seen before. Any information will be appreciated. Thanks 5 1 Quote Link to comment Share on other sites More sharing options...

Do you happen to have the breakdown by year? Also, does the Mack Historical Society keep records for these newer trucks like they did for the B-models?

JoeH Posted August 18, 2019 Share Posted August 18, 2019 Engine looks like an ENDT676, rated at about 283 hp. Engine tag should be on the valve cover or near the fuel pump... Likely has a 2 stick transmission: left stick is 1-5, right stuck is reverse, lo, direct. Quote Link to comment Share on other sites More sharing options...

I was thinking it was probably the 285 / 283 HP engine. I briefly looked for the tag yesterday. Lots of steam cleaning to do. It has a straight 5 speed with direct 5th gear. Previous owner said 59-60 mph was tops with current setup. Quote Link to comment Share on other sites More sharing options...

It may be an aluminum frame. I didn’t put a magnet on it and was painted kinda dark brown. I’m going to be on the hunt for a decent grill shell very soon. It’s hard working days are over. Shows and maybe toy hauling duties. Yes somewhat, that and I was a locomotive mechanic for 20+ years. 1 Quote Link to comment Share on other sites More sharing options...

No individual years or specific model But if you contact the Mack Museum with your VIN and a nice donation (the staff is 100% volunteers) you will get a good pack of info from the purchase order to the complete specs of it and sometimes the original purchaser. https://www.macktruckshistoricalmuseum.org/contact-us/ L - Light weight components S - Six wheel chassis T - Tractor 1 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...

It makes sense now. It’s been awhile but I actually previously had received all of the information about my 1953 B-model from the museum. I was very impressed with the package they sent. I’ll reach out to them again for the SL. 1 Quote Link to comment Share on other sites More sharing options...
