Yea I was going to say the highest factory rating you ever really saw any Mack engine(excluding E9) prior to the E7 was 350. The introduction of the E7 and more specifically VMAC probably is what allowed them to go above 350. You are also kind of limited with the 2 valve head......

Looks like you already found the proper yellow but I saw this in an old Sherwin Williams commercial truck paint refinish brochure at an antique store. I would have to guess the brochure was from the early to mid 1960s.....I don't think Sherwin Williams makes automotive coatings anymore though.....

Nice pre emissions day cab there. Mack transmission, light rears, air ride, over a million miles. You used to be able to pick something like this up for $9-12,000. They are asking $40k.....Crazy what the market has done lately.

Also will the injector lines all match up?

I doubt it. There is so much torque limiting programming going on that you will probably rarely ever get to use the engines "rated output". Emissions. Emissions. Emissions......

Not that it means anything but the Mack Website still shows 3 "performance specifications" for the MP8: Maxidyne, Maxicruise, and Econodyne. Honestly if you look at the horsepower and torque curves for the Maxidyne and Maxicruse there is almost zero difference. Actually, the Maxicruise makes slightly more peak torque at the lowest HP setting (415). If they are doing away with the Maxidyne I can see why. There is almost nothing different about it to justify its existence and affect on Volvo's bottom line. I'm sure their marketing people did a study and concluded those customers who wanted a Maxidyne would just take the Maxicruise if it was the only option.......

Don't you have to take it to a PA enhanced inspection station to raise the GVW if it has previously been titled at a lower GVW and/or if you add axles? When I bought my triaxle out of Virginia it was registered at 80,000 GVW and the PA notary made me get form MV-1 (I think that was the number) filled out by an inspection mechanic that stated the truck's setup was sufficient for 73,280 GVW in Pennsylvania.

Slow and steady wins the race LOL 🤣. But seriously another thing to look into is the gearing. A lot of these newer trucks have insanely (to me) fast gears to maximize fuel economy, or were specd to run in areas with no hills like the midwest. Put them in mountains with a full load and they will move the load but very slowly.....You could have one of those setups with like 3.08:1 rears......

I don't know what is cuter the little house or that short & subby little Kenworth. 😂

For some reason I always thought C.W. McCall was an alias or stage name of Chip Davis. I realize now that Chip Davis composed all his songs. Early in his career, Chip was working for and advertisement agency in Omaha, Nebraska writing jingles. C.W. McCall was a fictitious character for Metz's Bakery in the Omaha area. The ads featuring C.W. got so popular there Chip had the idea to compose songs featuring C.W. McCall for the radio and record label.......the rest they say is history. C.W. McCall's real name is William Dale Fries Jr.

This appears to be a super solid unit and checks all the boxes you you have listed (although he doesn't show pictures of the frame rails). Truck looks clean though so chassis is probably nice. I don't think its a dealer. He listed his phone number. Cant hurt to call him and see what he has to say..... https://www.ebay.com/itm/203882592760?hash=item2f785979f8:g:8hcAAOSw9OFiPvnw

Yea I figured that would be peoples' reaction. The way I see it the information contained in those binders is worth 10x or more of the asking price (if your willing to get your hands dirty). But if you come to the this forum looking for information I assume you are willing to do your own work. I guess it just depends on your wrenching abilities and how long you expect to keep the truck for. Whenever I buy a new truck or piece of equipment the first thing I do try to find all the available shop manuals and reference material for it. I tend to buy equipment and hang onto it long term though so it eventually comes in handy.....

I assume since you are asking about an E-Tech engine your DM is 1998 or newer. If that is the case the below link is to the entire set of service manuals you would need for your truck. They are not mine and I have no affiliation with the listing or seller. I just did a quick search on Ebay and posted the first listing I found. https://www.ebay.com/itm/373824134452?hash=item5709a79d34:g:77EAAOSwfmBgJtTl

Yea White Motors really sent a lot of once good brands/makes to their graves. Freightliner and Western Star got sold to Daimer, Autocar and White went to Volvo. Plus they destroyed the Oliver, Minneapolis Moline, and Cockshutt brands of farm equipment.

Found this browsing the auction listings. No affiliation with the listing just thought there might be some interest due to the ruggedness and good condition. This thing is immaculate. Very easy restoration or put back to work. Double frame is spotless. https://www.auctiontime.com/listings/trucks/auctions/online/213173489/1982-mack-dm886sx

I figured I would post up a quick few pictures incase the Ebay listing goes away.....

This thing has to be insanely rare. 1964 White Motors 6x6 in original condition. Owned my the federal government its entire life. Original mileage. Price seems steep on first thought but then again its probably the only one in existence. No mine and no affiliation with the listing. Just posting the link for others to see..... https://www.ebay.com/itm/353984459890?hash=item526b1e3472:g:PigAAOSwLEhiRa4i

Does it have to do with the motor mounts you are using and/or where the motor mounts bolt to the truck's frame? Perhaps there is variances in these that are causing the engine block to be located farther back. How much room do you have in the front?

Sorry but it was not me that bought them. It was @BGarofalo that bought them for $580/tire I think he said. I was just agreeing with him that they last longer than the Chinese tires in my experience. Personally, I run caps on my drives. For my application they are the best solution. I run very few miles and am operating at fairly low speeds. They last me a very long time. I purchase Michelin or Continental steer tires when needed.

Diamler Trucks North America. Its the North American arm of Daimler Truck AG, which is a massive German OEM that makes Mercedes Benz commercial trucks. Diamler Trucks North America owns Western Star, Freightliner, Detroit Diesel, and the former Sterling brand that was the former medium and heavy duty Ford trucks. I think Diamler Truck AG owns several different brands of trucks in different markets all over the world.

This. I can't stomach the thought of running the cheap Chinesium tires. Especially on a steer axle. A lot of guys say they are fine but I don't know. Look at the quality of everything else manufactured in that country. Why would tires be any different? They just don't hold up like a Michelin, Continental, Goodyear, etc. in my experience.

I agree. I still don't understand twin stacks on an inline 6 engine period....there is only one manifold. If its and E9, 3408 Cat etc. I can understand the use of twin stacks with those engines but even those I think join together shortly after the manifolds to go into the turbo. A lot of the new trucks with emissions and DPFs just have a dummy pipe on the drivers side that goes under the cab and is open ended. For looks only. My 94 RD Dump has a factory weed burner exhaust and I actually like it better than having a stack. I don't have to worry about the side of my bed getting all sooted up. Also I think its a little quieter having the muffler down underneath vs. vertically up next to the cab...If had a dollar for everyone who told me to put a stack on it I wouldn't need to work anymore 😂

I think its a supply and demand thing. A 425 float is a very commonly used tire available almost anywhere. They benefit from commonality and competition of many different brands making them. These 12R24.5s are fairly scarce by todays standards and not many companies make tires in that size anymore. The 12.00x24 is on a whole different level of scarcity yet. I think Bridgestone is the only "name brand" company left making virgin tires in that size at least available here. That's why you see such ridiculous prices on them.....They are the only game in town.

Its funny how supply and demand works. A Michelin or Goodyear in 11R24.5 is about $500 less than the exact same tire in 12R24.5. Is there really $500 less rubber and steel in an 11R24.5??????? WTF? At least you don't need 12.00R24s. They are like $1500 each now.

Man I was just looking at 12R24.5 and the options are extremely limited compared to an 11R24.5. Your basically screwed into $1200/apiece Michelins / Goodyears or some Chineseium brands with little to no information on. 12Rs carry about 550 pounds more in either dual or single configuration over a 11R tire. Have you considered going to a 11R24.5 or do you need the extra capacity?
