Screaming jimmy 2650rpm detroit diesel 671 get your ears ready

As a truck mechanic I worked on quite a few of these engines in the 70s, didnt matter if you were going 2 mph or a hundred they literall screamed and the oil oh the oil they leaked like a sieve. good memories

Please tell me im not the only one who notices how clean Lenny runs... no smoke at all.

I don't know what's more impressive .. the sound of it and the way it runs or the fact that there's no smoke at all

I drove an Attack Troop Carrier with two Grey Marine 671's in Vietnam. It was a converted WWII LCM where you had to handle 25 tons deftly using two D-handle four-foot joysticks. I would twist for power on each engine and shift forward or backward for differential thrust. You could pivot the beast very gracefully when needed. Like coming into a pier against a strong current. Many a night sleeping next to them while the night watch drove going up rivers and canals through the jungle. The 671 sound and smell is still hammered into my night memories. I remember dreaming about home then waking up to the nightmare - just the opposite of normal life.

I had closed captions turned on....at idle it said, "Hmm......" At 2650 RPM it said, "(MUSIC)"...... How true it is!

Best diesel ever made. Used in everything from WW2 landing craft to bulldozers, fishing boats, fire trucks and farm tractors. Won our war, grew and transported our food, fought our fires, built our infrastructure, caight our fish, you name it. That sweet GM music was the soundtrack to our cityscapes, waterfronts and construction sites.

Back in the mid 80's when I went to diesel school, the class of 12 split up in pairs and our class project was to completely tear down a 6-71, including the rack, reassemble it, and start it up on the stand. Since there was no oil or water in it, no exhaust system, and an open blower without the air box and trip plate, we were only suppose to run it just long enough to idle it and verify the rack was properly adjusted. About a minute. The teacher had made a steel plate with a handle welded to it to slam onto the blower in the event of a run-away to shut the air off. We got to the last motor when the shop phone ran and the teacher handed the plate to another student so he could answer it. The last two guys started their motor and the rack immediately went to full fuel. The guy with the plate dropped it and ran like he'd been shot! That motor ran for about 45 seconds before before we could get it shut down! You should hear what a 6-71 sounds like turning about 5 grand with no exhaust and an open blower! Yes, we all went home with stained underwear!

I can remember as a kid sitting on the engine hatch of fishing boat going out San Francisco bay with screaming Jimmy, at full scream. 40 years ago still can hear it today.

No engine, gas or diesel, will ever sound as wonderful as a properly tuned Detroit Diesel. I used to have a 6V92T in an Eagle and I loved going through tunnels or overpasses at 70 mph just to hear it run. Honestly I don’t think that the 6V92T was their best sounding engine but it was still sweet.

Could listen all day long I don’t think it’s possible to be tired of the sound

Detroit diesels make beautiful music 👍🏻👍🏻👍🏻

This engine's will run for ever Dependable and simple to work No computer B.S or plastic need it Thanks for posting this video God bless You all

Drove one of those screamers with a 13 speed for 12 years starting in 1971 . Hauled gasoline around western Pennsylvania , Ohio and NY. Exhaust had a 90 degree elbow just outside the passenger window and what a roar , loved it !!!

Military used to have a lot of them, old pre 70s HET had 16V92 with twin straight pipes, that's why I still listen to them today.

I had twin 8v53 Detroit's in my Chris craft. It redlined at 2850. I ran them at 2650 when I was out on the water. Had to wear ear muffs when I went down in the engine room at those rpms. Incredible.

Making me homesick, l drove Freightliners out of San Diego Ca for 8 years, straight V12 Twin turbos V12 and Turbo V892 Millions of miles 1972 to 1980

Growing up in Ca.in the 60's, we lived near the Cajon Pass and would hear those trucks going up and down the pass day and night. The sounds were incredible.

Love that sound!!! And I see literally zero smoke!

Even at low idle I find myself grinnin' ear to ear! Thanks for the memories! :-)

Back in the 70’s I used to drive an International Cab-over with an 8-71 under the Dog house right next to me. No wonder I’m almost deaf.
