That 12v71 alone is worth what he gave for the whole bus.

In 1973-74 I drove these Greyhound coaches from San Luis Obispo to San Francisco. The schedule originated in LA. They had the V-12 in them and would climb Cuesta grade in 3rd gear at 45MPH. The best speed you could get out of a Scenic was 32MPH in 2nd gear. I loved driving these MC-6's:):):) Another thing I found about driving these, is you don't have any sensation of speed. you'll be driving 65 MPH, it feels like you are barely moving. I had a local run, lots of freight, easy on the back. You didn't have to bend over much, like doing freight in a Scenicruiser.

"My first bus" gets the widest bus with the biggest engine, he's not messing around this guy. Nice. Swung it out of that park no worries either.

It's in great shape on the outside, so he can concentrate on the interior. Most of those old Sixes look like they've been through a couple of wars.

My heart was a flutter during the driving portion, what an amazing experience especially with headphones!! Sounds like the accelerator return spring was very weak as the rpm's remained high between shifts. Thanks to the internet and KZread, the MC-6 has gone from urban legend to a firebreathing beast of a bus!!

Wow! Started with Greyhound Canada in June of 1969. President of greyhound Canada was Bob Borden. He was so proud of the MC6. Us guys on the “spare board” did not get to drive them as they were usually on “regular” routes Calgary to Vancouver. I got lucky one day and was asked to drive one from Calgary to Vancouver that had brake problems! Taking it there for mechanical and break work for sure. Drove west through the Rockies, Rogers pass and the dangerous Fraser Canyon! Remember at that time very new exciting coaches. Needless to say. The trip through the Rockies with poor brakes was exciting. But empty with no passengers no problem. Stopped just west of Kamloops at a fruit stand and bought a big basket of fresh bing cherries to munch on as I drove the Fraser canyon. A trip I will never forget!! Would love to drive one again! Any in Western Canada?

I love the MC-6. Rode a couple when they were in US 'Hound service. They hoped for them to be the replacement for the Scenicruiser, but they couldn't get operating permits for the 102" width everywhere. Ended up running them on oddball routes where they were permitted. When they got overhauled, they got 8V71 and Alison automatics. They also (stupidly, IMO) lowered the suspension a few inches to clear the roof at the LA terminal. They should have put in a switch to allow lowering in and out and restore normal ride height underway. The lowering was not good for the ride and handling. The Canadians didn't have those issues. Theirs stayed 12V71 and manual trans.

Mercmad..... and these are "castrated" in these applications.... the sky was the limit (within reason of course) in On-Highway truck and marine applications. The 2 cycle Detroits (especially the Series 53 and 71 engines -this V12 is a Series71-or-71ci per cylinder) are very easy to make lots of power with, like "mouse motor" Chevy's are. The Series71 Detroits (like this engine) only have a 4.25" bore.. the same as a 400ci sm. block Chevy.... and a Total stroke length of only 5"...Total - keep in mind that these are 2 cycle, so from the total stroke of 5" you have to deduct 1" for intake port uncovering approaching BDC, plus (I forget the actual, exact amount at the moment) "approximately" another 18-20 degrees of crankshaft rotation for exhaust valve opening before the ports are "uncovered" by the piston, so these engines are actually producing the hp and torque they do, with Less than 4" of piston travel, and "Only" (small compared to the 4 cycle Cummins, Cat. & even the Mack, truck engines) 4.25" bore.

Wow 12 cylinder, that’s a sweet ride.

I never will forget driving an 82 Eagle through Charlotte NC(I-85). It had a 6V92T that belched so much black smoke that it’d make the noontime sun disappear. The bus was owned by a Christian ministry so the phone # was on the side & back of it. I had at least six people cuss me out going up the interstate plus the ministry ‘s office phone was lit up with nasty messages. It was a pre- computer 92 and the bus had been in the shop for a Diesel tech to address all the black smoke . He claimed it was normal. The 92 mated to a 740 Allison was a total pig. I think it would have been faster with a 6hp Briggs motor in it.

Now a V12 might make me want a detroit.... That would feel awesome to drive no doubt.

I've done Model 05 and 10 Eagles, by simply tightening up the leaks...mostly with new hoses to the evaporator and new O rings, then loading in a jug of 134a. Works really well!

The MCI / MC6 "SuperCruiser's" were All powered with the V12 (Series 71 - NA / Naturally Aspirated) right from the beginning, Except for... one of the Two prototypes, which had a Mercedes V8 (was later, scrapped). Both of the two prototypes had sheet-metal (body panels) covering the Non-powered tag axle.... the production units of course, did not cover them. As far as the use of twin Detroit 4-71N's for power.... you're thinking of the GM PD-4501 Scenicruisers (built between 1954 & 1956). The twin 4-71N's were used because the 6-71 was not powerful enough (at the time) with approximately 165hp with the HV7 injectors, for a coach of that size and it wasn't until 1957 that DD released the first "V" blocked engines, including the 8V71. The two prototypes (GX-1 and GX-2) for the PD 4501's were powered with 6-71N's. Personally, I don't know why GM didn't use the 6-110... it weighed about the same as the two 4-71N's that they used in the production units starting in 1954... about 4000+ lbs, had 275 hp and more torque than the 8V71N had. After the 8V71 was released in 57 and proved themselves, all the PD 4501's were converted to 8-71N's. Back to the MC6.. there were 100 built, 15 remained in Canada and 85 came south to the US. When they were shipped to the west coast, around 1977, they were all converted from the V12, to the 8V92TA (in production from 1974), which probably were rated at 435hp which was only 1 hp more than the rated 434 hp for the 12-71 (with N60 injectors), and the original Spicer and Fuller manual transmissions, were replaced with Allison slush pumpers (automatics). All 15 MC6's that remained in Canada retained their original power trains until retired, so if you see an MC6 anywhere with the V12, it's one of the 15 that remained in Canada.

Try Steele Rubber Products for vista window seals. They make custom for classic, vintage and hot rods.

The buzzin’ dozen! They seem to lope for the first minute after a cold start, then suddenly smooth out.

Buzzin dozen 👍🏻👍🏻👍🏻

Sure is a really neat and extremely rare bus! Is only 100 made I doubt more than 20 are driveable but that's just my o2. Btw hope you do keep in contact with him maybe help him with the engine or the bus. You seem very experinced.

Love that power!

My guess is the reason it won't return to idle, is because of a sticky pedal from sitting. That's an aluminum pedal, and the pivot pin is steel causing oxidation through electrolysis. The fix? Press out the roll pin that holds the pivot pin in, using a pair of channel locks and a very short punch, pushing the roll pin through the pivot pin. Remove the pivot pin. Run a drill (same size as the hole and not larger) through the holes on both the pedal and the mount removing the oxidation. reinstall using Never Seize. If the throttle was slow returning to idle, I'd say it could be the buffer screw is screwed in too far, however, if that was true, the engine would not be rolling at idle, like it did, so I doubt that's the problem.

Music to my ears ! Awesome bus brother, I have a Blue Bird Wanderlodge diesel pusher, cat 3208 turbo...

That thing sounds beautiful man I've never heard a 12v71 engine like that before love that sound

Classy Punisher sticker on the yellow dodge!

Love the BUZZIN DOZEN!!!

First thing to do: lube up that throttle linkage! Not only dangerous but makes it impossible to time shifts....

Bus Grease Monkey hi Scott, great video as always! this guy scares me with how little he knows about his bus! haha. What’s the squealing sound as he pulls away from standing each time? Keep up the good work, we love following along! Chris in the UK 👍🏻
