Look on marketplace in the southern states like Tennessee, Georgia, Mississippi, and Alabama (if your willing to travel). Old, single axle lowboys are very common down there for like $2500. It must have been a regional thing because I never see any up here unless they are hooked to an antique.

Pretty much everything except for the "killer dowel pin". Its a real thing. A place I used to work at a long time ago had the exact same setup truck. 12V 5.9 with a Spicer 7 speed. That stupid dowel pin wiped out the timing gears and the front of the engine. It had less than 50k miles on it. I think it was still worth enough to them they put a reman engine in the truck. I would pull your timing cover and see if yours has been addressed already and if not fix it. Its a very easy job and like a $50 part.

I bid on it up to $2250 but I had a feeling it was going to go for a lot more than that. I watched this action on and off all day and the amount of money these old original porcelain signs bring is insane. $15,000 - $20,000 is not uncommon for some of the oil and tobacco signs. They don't necessarily have to be large. This one would have been really nice to have and looked excellent on my shop wall, but I'm in some ways happy I didn't buy it as I can honestly think of much better ways to spend that kind of scratch.

Sold for $5750.00.

Why not try dealer?

I get it. That is why I said a very easy to see example. In this scenario it could be 800miles, 8,000 miles or maybe 80,000 miles. We will obviously never know but a difference in life span is theoretically there. I only bring it up because the OP questioned it. If Vegas was taking bets on the maximum lifespan (miles travelled) of the 355/380 versus a 427 or 460 under the exact same loading conditions the odds would be in favor of the 355/380 because there is a scientific basis as such.

From a physics/engineering standpoint this is untrue. If you have two identical engines aside from the amount of fuel/air delivery to each, operating under the same load conditions, then the engine with the greater power density will fail sooner. A very easy to see example of this is a top fuel dragster engine. Around 500 cubic inches making about 10,000hp. The same exact engine making a modest 500 hp would theoretically last much longer subjected to the same load being applied to it. Obviously at the expense of much more time to do the same work. An over the road truck engine is no different but much harder to grasp the longevity difference between the two.

I knew of a guy that got in an argument with a parts store guy about parts for a GMC with a 305 V6….the parts guy swore up and down no such animal existed and that the only 305 in a GMC truck was a V8….this was like 15 years ago and you would have thought the guy behind the counter would have known better as he was I guess in his fifties at the time

Did she at least sell you the battery?????

Yea I saw that yesterday and almost posted the same thing but refrained. The owner is full if chit. Once you deduct for all the wood and tires you are probably looking at 7,000-8,000 pounds of iron. Unless you cut it up yourself into small pieces yea you are going to get $5/100 for it. The thing is worth $400 - $500 in scrap.

The other thing to note with push connect fittings is they might not seal in vacuum systems. Some shop installed one on the fuel suction line of a series 60 Detroit I once had. After a few miles it developed an air leak and would not stay running at idle. Replaced the push connect fitting with a compression style fitting and the problem was solved. Did I get a bad one or are they just not meant for vacuum? I don't know the answer to either question. I stay away from them if I can. As far as brands I think Parker is one of the biggest name in brass DOT fittings both compression and push connect.

Is there a part number on it. They are usually very faint and this case covered in thick paint. You may have to take it off and remove the paint see if there is a number on it. If there is you can probably figure it out that way. From your description it sounds like a relay valve to actuate something else when the brakes are applied. Since its connected to tank air at the top. The signal air from the brake valve probably opens a port inside the valve and allows the tank air (top line) to send air to something else via the port that is plugged (right port). Once the brake application is relapsed the air is exhausted through the bottom. A lot of relay valves are also regulated so the air sent to whatever it is controlling does not get full tank pressure.....just depends on what its controlling.

Go to any of the online vendors that sell only heavy duty truck parts. There are many. AnythingTruck.com is one. McMaster Carr has a decent selection of DOT fittings and tubing. Dealership or independent heavy duty truck shop parts counter is an option too. Personally I would stay away from the push to connect style fittings if possible.

How would you like to be the pilot that shot it down. What a story to be able to tell your grandkids. "I was the one that ended the great Chinese spy balloon scare of 2023!"

To me the whole balloon thing seems quite comical. The entire nation is hysterical about a friggin "spy balloon". What are we living in 1920? Clearly the CCP has an extremely advanced global satellite network capable of much more advanced surveillance than a balloon would be equipped for. So what really is it? A weather balloon? A decoy? A joke? Besides its not like this is something new. At least two CCP balloons traversed US airspace during the last presidential administration we were never made widely aware of until now. How is it the former president, who was widely labeled the toughest president ever with regards to China, never thought to tell us about two different balloons supposedly "spying on us"? I'm speculating the difference this time is it was clearly visible with the naked eye to ordinary citizens. Social media took it from there. They spy, we spy, everyone spies. Constantly. Nothing new there. My guess is if it truly is not just a weather balloon then it is a stimulus to see what, if any, the response to it would be. Probably with some super low grade video, photography, and/or listening hardware installed for good measure. If my guess is correct then they got the information they were looking for. If not then the CCP obtained some more pictures of the different architectural styles Billings, MT has to offer. 🙄

Couldn’t you just unload like 5 mowers if you’re still collecting them? Trade 5 mowers for one Mack? Haha. You could say you got rid of 4 things. Sounds real good

Where was Pittsburgh Mack back then? Same location it is now?

Well I tracked Dan down on the forum here and send him a PM to check it out. Hopefully the message finds him and he has the time to at least check this one out. I don’t know if he gets on anymore or not…..I know at the end of the day it’s just a Ford cab (I think) with a Mack badge on the front but this truck should be saved….

Isn't there a big Mack guy on the West coast.....Oregon I think. He was featured in Wheels of Time Magazine about a year or so ago. He has a pretty nice collection and does all the restoration. Maybe it would be up his alley? Not that Southern California is all that close to Oregon but worth a shot for a rare model maybe? I'll have to dig for that edition of WOT and see if I can find his name. Maybe someone on the forum knows him.

@mowerman You should slip over to LA and drive this baby home. Be like the good old days. It needs saved and you could be the guy to do it. LOL

Denny, Also let me know if you are interesting in the below lead. I visited this place in October and he had a bunch of stuff. It is out of your search radius though...

On a side note: how rare is a G-75? I don't have any knowledge of the model or production numbers. In fact I think this is the only one I have seen on the forum in my 3 years here.....at least that I recall.

It does have the B61, Thermodyne, and Diesel emblems on the hood. Are we suggesting it was repowered to gasoline or the hood from a diesel was installed on it sometime after it was new? Both seem far fetched considering it is owned by a municipality.......Its a diesel.

Dennis, Try these two outfits. One is in Pennsylvania and one in Illinois. There may be others as well. https://www.rushgears.com/ http://www.circlegear.com/index.html

I said this in the other post on this truck. It's probably a "non-runner" because nobody there knows it has an air start. The guy that drove it probably retired 15 years ago and has sat ever since. Now the new guys want to unload it. "Hey we put a new battery in it and turned the key....it wont start".......non runner
