Greetings from Oregon...

Just purchased a 1974 Blue Bird with a 432 slanted 6 @ 60. Looking forward to the new adventure, also looking forward to meeting other likeminded folks within the state.

Congratulations from Oregon
Oh, we're going to need to see pictures of that slant in your old Bird.

I've got a '72 Ford 5 window with a 300 6cyl. It's kind of a take the old highway kind of thing, but it works. Now I bought something more capable of interstate travel I'm hoping.
Where do you hang your hat?

@Robin97396- Greetings! At the moment my hat hangs 8 miles north outside of Monroe. Or 7miles south of Corvallis....lol... We're a family of 4 living in a 18ft 5th wheel. So needless to say the 35ft BlueBird should accommodate us better. It needs a bit of work, nothing impossible tho. She runs at the moment and is in need of a mechanic that has worked on the type of motor we've got. I'm willing to bet all she needs is a good tune up. We're looking to renovate so that we can live in it year round. The housing market isn't going down and it hasn't been easy to find something within our budget. Buying a piece of land that we can work into our own seems to be the most logical way to become homeowners, eventually.

@Cadillackid- It is a slanted V6 @60, running on gas. Not sure yet about the chassis. Will gather more pictures and info this weekend.

@Maffei- Nope not in Silverton. The bus is near Jefferson. On a property tucked away.

Awesome! We bought a shorty back in August and are almost done converting it into a weekend camper.

We bought our bus in corvallis, and I believe there is another skooler in corvallis with a shorty similar to mine. We are everywhere around oregon....

The most likely engine would be the big block GMC V-6. Blue Bird put that engine in a LOOOOOOOOOOOOOOOOOOT of buses in the '60's and '70's.

I am trying to remember the sizes. 401 and 478 come to mind but not 432.

If it is the big block GMC V-6, those were not bad engines but they had some odd quirks.

First off, they had an extremely narrow power band. They didn't lug well and once you went out of the top of the power band all you were doing was making more noise and burning up more gas. I never drove one with an automatic. With just a 5-speed you spent a lot of time going slow up hills. A 5-speed with a two speed rear end gave a little more flexibility to stay within the power band.

Second, they had some real balance issues from the factory. They were famous for breaking ears off of the intake manifolds, cracking air compressor/alternator/power steering pump brackets, and shaking the carbs to pieces.

Third, they tended to run hot. It was partly due to the fact they were made out of a LOT of cast iron. And it was partly due to the way in which the combustion chambers were designed in relation to the water jacket. On a long hard pull on a hot day you could get the exhaust manifolds cherry red if you weren't careful.

Fourth, the plugs were in the valley between the intake runners. You had to be very careful when changing plugs that nothing was in the valley that could roll into the spark plug hole. Don't ask me how I know that can happen. The same basic block was used for the Toroflow diesel engine. The only differences were instead of plugs you had injectors, instead of a ignition distributor you had a distributor type injection pump, and there was no carb on the top of the intake.

By the '80's it was an obsolete motor and as a consequence the parts started to become hard to find. This many years later it could be a real hunt to find some of the engine specific parts like the water pump.

In order to make driveability better and the hunt for parts easier it might be a good idea to invest in a modern electronic ignition and fuel injection system. I know there are kits out there that would fit one of those engines. I have no idea where you would go to find some of the carb parts for one of those engines.

Good luck!
