Deborah Chesser How do women know of Detroits I grew up around trucks as my father was a truck driver. 8V71 is best sounding of them all in my opinion.
That is the second Mack I've seen with a "Jade Grenade". The first one I seen was when I worked as a Fuel Jockey at a Husky truck stop. A guy who owned a late 70's Mack Cruise Liner (Motrux Transport) used to come in for fuel. He ordered the truck from factory with a "Jade Grenade". I did not know this was special until one day the truck was at the pump and some trucker come up and said "WTF??? A Mack with a Detroit?" And the owner said "I ordered it with the Detroit". I've never forgotten that to this day.
This takes me back. I drove an RL-700/Detroit/RTO-910 back in the mid-70s. I used to haul steel on a 40' flatbed out of U.S. Steel's plant in Fairless Hills, PA. The trans was so sloppy that it would change gears with a good slap of the shifter. Good times...
Always great the hear an old truck scream going down the road. These newer trucks just don't have an authentic sound to them when they're on the road. Stay safe.
ballston ? truck show its next week i have to go! i love these old trucks driven many of them been going to ballston since 18 years old 47 now i still wont miss that show
DW lip yes I stuffed up but there is a yellow superliner single drive with an 8V92 never seen nothing like it.It's bizarre to have a 2 cycle in a Mack but they did it in Australia as well and not just the highway models.Although the Mack guys were very reluctant to fit a Detroit motor in the factory even though it was an option. In a factory in Brisbane they used to put covers over them so the diehard Mack customers couldn't see what engine was in it.
Mine was an R797.. with the Mack 375hp.. had the triple counter shaft 12speed , 5.32 diff, so changed that for a 4.1.. the 375 packed a sad, so repowered with the 18R.. much better toque and fuel economy .. had a 4inch stack on the muffler up behind the cab, the drone flippin started to piss me off.. so with a short reducer to 3 inch.. much better.. had artillery wheels, changed them to tubeless, loved it....
WOW! Now that was different! As most R model Macks had the inline 6 cylinder engine. However that is one mean sounding Detroit Diesel under that Macks hood! Hope he restores it!
@@mr7badass they are great when your batteries get low I know that for sure. With a mechanical motor and air start there’s no electronics involved at all, ya gotta love that.
Great video. I'm 62. I ain't askard!!! Love those old trucks! Grew up watching them and started driving trucks when I was 20. Big trucks and trailers around 24 year's old. Yeah, I've heard that the only way you got a Detroit was a special ordered truck.
Engine will run backwards just as good as it runs forward. Get it in a bind and almost choke it out. She will catch back up running backwards. Seen it many times.
black truck looks like a brockway. So.... nothing moire American than driving a brockway, smoking a cig....... with a detroit under the hood..... with a mack on the back.
Never sure why the R-700 never sold well. They usually had Cummins or Detroit in them. Guys who had lots of Detroit powered equipment like cranes and draglines bought them because of the parts interchangeability. Lots less parts to keep in stock when stuff fits everything from a 2-71 in your light tower to a 16v71 in your 20 cubic yard shovel
I don't know which part of the Country you live in But the R7 sold as well as all the other Mack models and were sold mainly to Fleet corporations like say for example Mystic Bulk carrier's and Pro Van bulk haulers you could get them with just about ANY power plant you wanted and even the Mack Maxi-Dyne as well .. These are the very back bone of building America they were NEVER supposed to be the most Chromed or best riding longest hauling these were Regional Grunt if you needed a Bridge built Or Thruways system installed Mack was there..The closest they ever came to over the road I think was the Superliner at least back then ...
@@TheRoguelement I spent most of my life around Philly Pa. Lots and lots of R685ST and R686ST tractors around, All pure Mack specs. Lots of used Matlack and Chemical Leaman trucks around. I'd say about 90% of the Macks were almost pure Mack with the exception of some with Road Rangers in them. Now I'm up in the Anthracite Coal area, The R600s were real popular tractors here too. Mostly speced all Mack with TRXL107 transmissions. We have one here an 86 , 285 , 6 speed, 38 rears on Camelback 122,000 original miles. It's our shop truck. It's spent most of it's life indoors. We're 2nd owners. When we bought our building from an estate, we bought the truck from the same estate, So it's really spent it's whole life in the same garage
@@cindytepper8878 I lived near Philly until '81 when I graduated and remember all of the Matlack, Chemical Leaman, A. Duie PYle, AAA, etc. R600's. The R700's were popular back then in the west where the length laws weren't so restrictive, but you are correct that they weren't common on the east coast.
One reason is setting behind one all day long is brutal! If you have never done it. Man it's bad. No matter what mufflers you put on it or how tall the stacks are. It's bad because if you're moving she's screaming
I don't know why this showed up in my recommended list, but I watched it, and now I want to buy one of these trucks and tool around the U.S. in one. Such an industrial looking truck! Now if it came with an air-starter.... :).
Well done guys! If any truck should carry the adjective “sporty,” it’s certainly Brockway with this engine. And even his steering wheel is sporty 😎 Greetings from Croatia!
When I was a kid my Dad had a cabover Mack, a 1970 I believe, with a 350 Cummins and a 13 speed. He previously had a 66 R model with the twin stick 10 speed. His first truck was a Ford gas burner with a 5x4. I think it was an FE style engine, maybe a 532 Cubic Inch. That was a long time ago. LOL
Yeah. My dad was a diesel mechanic and took me on a ride when road-tested one after repairs. He used to take me to work with him on occasion at the request of my mom so she wouldn't have to try and keep an eye on all us. I guess she thought getting one of us 8 kids out of the house on a summer day was a little rest for her. My first view of a Thermodyne with a twin-stick, this was in about 1962; I was 14 at the time.
Hey the guy with the Brockway and "Eager Beaver" float, just hauled a single axle Brockway from another utuber "Walter Gorzkowski". Minty cab ride. Love the sound!
Flip side 2005 mac/volvo vision unrelaible no speed demon doesn't want to pull Its on weight compared to 99 Mac no speed demon tons of torque all day very reliable that's been my experience
I almost never post a negative comment so I will say that from a collectible standpoint it has value but as an owner of trucks for over 40 years including 2 stroke detroits and 237 and 300 R models this is a ridiculous combination. A 318 will never pull with a 300 maxi. Been there. So many positive comments about the old Detroit’s but I imagine if those folks had to gross 80,000 and drive thousands of miles through hills and mountains they wouldn’t feel the same way. I love the R models but with Mack components front to back.
I think RU-vid has created a following for the old Detroits. Ive talked to so many old school guys that cant stand them, or at least say they are not designed for road trucks. They are stationary, equipment or marine motors in my opinion. Not denying that milions of tons have been moved with them i just dont think they are best in on road apps.
Nick the Mack engines were about 200 ft/p more torque than the screamer and over a broader operating range an 8V71T would go better or even 6V92TA 350HP/ 950-990 FT/P
I kinda agree with ya. My dad's oilfield company had a Mack model R with a straight 6 Thermodyne and 6 speed 1980 model I believe. It was a pulling sob!! 80 mph with about 60,000.
That’s a real Allentown R model Mack ! They didn’t ever get better than that ! It all went downhill with the Renault buy out and Macungie. Mack’s are absolutely nothing but rebranded Volvo Trash these days. Glad you found a real one !
