Detroit Diesels & GMC SEMI Trucks 

This guy is so right about the way the extra fuel pressure on certain Diesels will ruin certain the injectors. Not everyone will like to hear this but he is 100% correct

We fade away but never gone 👍🙏

Awesome to see a Southern Detroit man thx Billie

Final last words and the best, "I decided to keep that one"!😉 1.2 million on a 8V71 and that is why he got it there. Maintenance is king and the and he is absolutely correct, 9/10 won't do what they need to do until it breaks.

Another benefit of the V configuration was that it made re powering gas powered trucks a viable option. Harper Detroit Diesel in Toronto did scads of 6V71 retrofits in the 60s, mostly on F series fords. You could even shoehorn an 8V71 into an F series. I drove a 67 F850 with an 8V71 in it for a while in the early 70s. I blame most of my hearing loss on that truck.

This guy is a treasure! And the best part is by watching you talk to this man you can just tell by the look on your face that he is a trove of historical facts and information. Just like a real encyclopedia and no index just ask awesome stuff! 🧐

Sorry for your loss Dane. It was so cool to hear Billy talk technical Detroit, that I thought I would like to ask him a question ? i'll trying to make it short ! I had a 1973 GMC Astro that I bought in about 1977/78 with the 8V71T, the GMC dealer told me that it was an experimental truck that they were were leasing, it was really decked out even had a side cluster of gauges for the pryometer and rear and transmission gauges ! Anyway, it was hard starting cold 50 degrees u needed an either pill, once started it smoked like hell even after it warmed up ! I had her for several years different Detroit Diesel mechanics, check valve lash, injector timing, and so forth, they couldn't figure it out ! One morning on the way up to Detroit, snowy rainy morning around Battle Creak I started loosing power, glance in my right mirror and there was this cloud of black smoke behind me ! Pulled off in the shoulder loosened up one of the intake clamps and stuck my screw driver in between the rubber and intake pipe and heard this huge intake noise , ok, so my filters plugged ! It was a Donaldson side draft air filter (driver side with intake louvers) ! No one in Battle Creek had one so I took out the top filter and proceeded up to Detroit ! Many years later still wondering why she was so hard to start, when I realized that maybe the blower was worn because the previous drivers did the same as I did maybe more than once !! We never check blower pressure?? What do you think Billy ? Thanks Dane

The preempt is good stuff!

I have a friend of mine who is a diesel mechanic right out of high school in 1976, his dad was a trucker, he told me if you take the injectors out of a 8V 71 put them in an 8V 92 and change the governor linkage around it will break the wheels loose of you stomp on the throttle. 855 Cummins and 318 (8V 71) will just run shy of a million. He is exactly right about running conditioner and adjusting the valves and taking care of them, but I know some guys were doing inframes at 500,000 on Cummins and Detroit. This gentleman is very knowledgeable he was dead right on everything.

Love your channel my grandfather had 3 rigs my favorite being a KW cabover ,did I mention he loved Detroits, and I do heavy haul now, keep up the good work and I love the GMC song

I have appreciated this whole interview of this man!

6V71s were promoted over the inline in the late '60s because of the weight advantage of 2-300 lbs. Then with more interstate running , the dry block 6V started having more failures with the max injectors [N-65]. Block would warp, requiring rebore and oversize sleeves. Same problem existed on 8V, but not as frequent, especially if freight companies settled for 260 HP N-55, or 290 HP N60s. I've parted out a Roadway 8V engine that had 7iN5 bus calibration that equaled N-50 , for 245 HP rating . Bigger engine weaned down gave longer life.

I'm so sorry for the loss of your friend. 😢

Sounds like a engineering grad, good man!

Sorry for your loss buddy...

O-H-I-O Porters here.🇺🇸 Blessings & prayers to Ron’s family. Billy seems to be a character! I agree that you should keep your engines tuned up, especially if you run them hard. Nothing like a tuned up Detroit or Cat engine. I might have to see him about my Silver 92 engine when I get that truck. It was so good to listen to you guys. Thanks. Good stuff, as always.🥰😎✌️

Sorry for your loss brother.

So sorry for your loss buddy I loss my pops back in June of 2022

Sorry for your loss Dane, Enjoyed the video and input from Billy Parker.

My Condolences Dane

Sorry Dane, I just remembered one more thing, I rebuilt that engine 3 years after I bought her, even rebuilt the turbocharger and she still smoked at idle, and was still hard starting cold !! Ran great otherwise, I still remember getting 3 miles per gallon, I was pulling three nines, steel hauler of course ! Detroit's were always easy starts but this one, I still think it was that air filter ! Thanks again !! Bernie ( the Tasmanian devil ).

Sorry to hear about mr.greer.i know what it's like to lose a good friend. I did not know that Detroit diesel built a air cooled engine. The 60 series was good motor for the 90's.

Jeez that is rough

I’m really sorry to hear about Ron ‘s passing, & my heart felt condolences &Prayers are with you all!

Good to see Billy in the house. Nice conversation you guys had sorry about the loss of your friend.

Sorry for your loss Mr. Scott..

I’m sorry for your loss Dane, sad that we’re losing friends that were a wealth of old school knowledge. I wish you could’ve known another old school guy, Jim Bowser who was a very good wealth of Detroit knowledge. He was friends with Larry and Jeff.

Sorry to hear the loss of your friend Dane , R I.P. to him and condolences to his family , SAFE TRAVELS 👍👍👍👍🙏🏼🙏🏼

OKAY NOT COOL I NEVER WAS NOTIFIED ABOUT THIS BYE RU-vid I HAVE MY NOTIFICATIONS ON TO GET WITH IT RU-vid. HAPPY HOLIDAYS Dane and family 🎄🎁🎄🎁 ps sorry for your loss PRAYERS for the FAMILY and friends 🙏🏻

When I was growing up I was in love with semi's. One that I came attached to was a a late 60's F-900. It was built as an auto carrier. My friend as of today still, removed the carrier equipment, it's original engine, replaced it with a Detroit 6v71 and added a dump box to the bed. I put many many miles in the cab of that truck. My other favorite truck that had a Detroit was another one built by IH also was a former state owned dump truck.,

These Trucker Lounge interviews are a great source of information.

Sorry for your loss Dane. Rest in Peace driver.....

I know how you feel I lost two bubby's this. Year too hang in there friend they are trucking up there with the big guy be safe thanks again for the video

So sorry for your lost . He gave you some good memories , he will live forever in you mind and memories.

First time viewer to your channel and owner of a '93 Newell coach with a 8v92. First and foremost, my condolences for the loss of your friend. Sounds like he was an amazing guy. Hang in there.

Thank you for talking about RON, my heart goes out for a guy that will get an older model Class-8 and drive it 14 days so far. May he rests in peace, so sorry for your loss of a great guy who knows an older truck. The stuff he knows in his brain is hard to replace for guys & gals who love older Semi's. I own a (353) in a piece of Heavy Equipment. I also own a (8-71) in a 1971 SeaGrave Fire Engine. I Love Detroit so much, bought my first GM (Chevy) Duramax Allison Diesel Pickup. Always been a FORD driver. My last two pickups (always 8' beds) My first NEW pickup (1979 Ford) gas (351) Second pickup a 2000 (V-10 Gas) looked at the Cummins hard, but the boy was stuck on the Duramax Engine with the 10 speed Allison. Saw cut/down transmission blocks at the Allison booth at Con-Expo Con-Agg in Las Vegas. Loved it that Garbage haulers and FDs use that very heavy duty Transmission. This 2021 Chevy-Z-71-3500-4 door-8 foot bed,I love the pickup. The Diesel fuel mileage is out of this world. My wife BEAT the BEST mileage on the dash reading almost 32 M.P.G. coming down a mountain pass in my state. 31.7 M.P.G. for best mileage. It gets up to 22 M.P.G. on freeway driving. The heavy traffic, Stop and go Rush hour, it drops below 10 M.P.G. like my Ford Gas hogs got on all driving. My 1979 towing a 22 foot U-HAUL with washer and dryer, plus a piano for my parents move, it got 10 M.P.G. same fuel usage empty or full load.

That gentleman looks familiar and I am saddened to hear this! Sorry to hear this I have my hat tipped this morning as I get ready to go over my pretrip of my service truck. 3 minutes he will get your friend he will starting at 4:27 am! Now. God bless you and his family! 🙁

Hey buddy good to see you again buddy see you soon

Sorry for your loss. Great conversation with a very knowledgeable fellow.

Prayers to the family sorry for your loss

Very cool and informative video! Sorry for the loss of your friend. I'd love to sit down with Mr. Parker and talk old trucks! I've heard his name cause we don't live far apart but never met him. He seems like a great guy with lots of cool stories! Looking forward to the next video!

Nope not air cooled as a 2 stroke it like air induction. Like a weed trimmer chainsaw etc. Theirs ports in the lower liners that allow forced air into the cyl. That takes care of the fresh air in the compression stroke and blows out the exhaust in the cycles. Soo yea

I loved the old Detroit diesel when I was a kid. When I was in college I worked for a gravel pit. I mainly ran a1953 Euclid belly dump."wheel wind" with a straight 6-92. It had no cab. But I had more horsepower than anyone out there. Keep up with your oil.

Need more of these talks and have them last longer.

Talking about Detroit Diesel engines I wonder how confused you could make a person if you told them that you had a 736 under the bonnet or the cab of your truck

Great to see Billy again he's seems to have a lot of nolage. Sorry for the loss of a friend,,,friends are hard to find RIP Mr.Greer

Condolences on the loss of a friend. RIP Ron.

So sad about Ron we seen him in your videos Dane he was a awesome guy loved his ASTRO Aswell our thoughts and prayers go out to his family and are deepest sympathy go out to you Dane so sorry for your loss he was your good friend and he will be in heaven waiting for you when you're time comes God bless you in this difficult time

Detroit’s are the best!

Thanks,I appreciate the information,it was very interesting.I have to ask, what was the last year of the two cycle Detroits ?

Gotta Love those GMC 9500s

I am so sorry for the loss of your friend Ron. My condolences Dane. 😞

An engine is that uses heat to make work.

Rip Ron

If it's any help 8V92T produced 1,186 LBft of torque , stock output

I'm sorry to hear about Ron, I'm sorry for your loss Dane.

Great interview Dane. Glad you had Billy back. You both are interesting characters..

Sorry to hear this Dane, i know all too well what you're feeling. On a happier note I do love the sound of a 8v71. Road in a 66 needle nose w900 that had one and man did it scream. It's still around my area sitting in a shop. Would love to do something with it someday but thats up in the air right now.

I didn't know there was a air cooled version

Like #37. That was a superb vid. You could have went an hour talking to Billy. "Wisdom" is always captivating.

I just picked up a RT 915 15 speed transmission for my 1985 359 peterbilt big cam 3 Cummins

Rest in peace Ron, I'm sorry for his passing.

His Brigadier is nice and 8V71 power , oh yeah

Great interview, well done!

There is some small differences between the 6V71 and the inline 6-71, the no load RPM of the inline is factory set to 2100 RPM, the 6V 71 is 2300 RPM

Dane great video sorry to hear about your friend

.DETROIT DIESEL NA VEIA!

That was a really good video very interesting it would be nice to sit down with Billy and talk old school trucking with him very informative man

I always felt like the 2 cycle Detroit's fell on their face on a grade. Couldn't completely understand the cult following except for the unique nostalgic sound. Your guest, some bus RU-vid channels, and reading has given me a real education on their real value and GM's success. Great video. Sorry to hear about your friend.

Hi Dane. Sorry for your loss As a fellow enthusiast of old GMCs here’s a little story My dad use to drive for Cooper Jarrett (Being from Ohio you may be familiar ) I remember my dad laid a Astro over in Napoleon Ohio and the engine started running backwards. How’s that happen? Love your channel

Wow there Dane, did you bottle up all the great Detroit knowledge from Billy? I enjoy your chats with him. Sorry about your friend Ron, RIP good buddy!

👍👍👍👍👍
