This one had been a four speed,IIRC it was sent out by Greyhound for conversion before they retired them ( engine,trans. etc.) i wish i could remember,but i think it originally had 2 V-6 detroits in line? it was a very early production model,and i was told they were very problematic,next time i talk to my friend,i'll ask him more about it............................Mark

Hi there Mark,

PM me if you get more details about the 12V installation, never seen one but there is fokelore about one.... and one with a Mack engine quietly tested by GM in Germany of all places..!!!

I have two Scenicruisers, one is being restored to a level just like in the video... tough slog restoring buses, should have stuck to trucks..!! (ask Matt Pfahl)

the original design from 1954 was two 4-71's in parallel mated hydraulically to a single trans and two speed rear axle... an absolute pita for everyone, Greyhound sued GM... in 61ish all remaining coaches were converted to 8V71 and 4 speed spicer and regular diff... this was done by Marmon-Harrington.

to install a V12 in the engine bay would seriously cut into the bulkhead, a very weak feature on a good day and the cause of the many "boiler plate" additions to the sides of the coach in years to come.

from my memory, the only highway coach that had a 12V71 from the factory was the MCI MC6...

Post some pics of your restoration. I also think a bus would be a MAJOR project. Good luck and looking forward to seeing the finished bus!

Hello Farmer 52

thanks for your interest in my non-Mack project, I hope I'm not taking up too much bandwidth talking buses...

of 1001 built, 250 still exist but only 25 remaining with seats, hatracks and toilet still in place... it has become one of the "collectible" buses. The one in the youtube video is owned by a guy in the UK who flies over to the US on his vacation time to work on it, the bus was painted in the UK and shipped back to the US to be finished off as he couldn't find any skilled staff over there.

I've put thousands of hours into the restoration, started in Feb 2008, nearly every weekend working on my own, still 18 months or so to go... (then I finally get to work on my MH)....not something you would send to a shop to do, however, Matt Pfahl is undertaking one right now and it will be the most extensive resto ever done on this type.

I hope the pics are of interest, and, to satisfy all 2 stroke fans I will pour two gallons of dirty oil on the engine to get that 'authentic' look.... :loldude:
