1966 GMC Short School Bus questions

I'm looking at a 1966 GMC bus. Owner says it has a V6 Chevy engine that is locked up. What engine might that be and would it still be repairable? Or what type of replacement engine would swap in? The bus has a Superior 24-pass body. Is that a good body? I like the size of this bus (21 feet long). But wondering what problems confront me in having such an old bus and where I could park it. My HOA prohibits such vehicles. Lastly, the bus is still yellow which is illegal in my state, how do you paint a bus? Can I just brush-paint it. Thanks.

Most of us are dealing with much newer machines.
Lots of the buses of that era had six cylinder gas engines. My buddy has a 66 Ford with an inline six. Also locked up. He uses it as a storage shed... We got it free from an OLD hippie.
The problems you'll run into are the same you'd run into restoring an old car. Everything rubber is usually GONE, every aspect has to be addressed, and lots of rust repair and bodywork.

superiors liked to rust badly... superior went out of business in 1981 so parts are near impossible..

a locked motor.. anybody's guess if the block is destroyed or not.. often a locked engine is due to a spun main bering which destroys the bearing cavity in the block..

if its a chevy engone and a chevy bolt pattern you might be able to drop a 350 or a 454 in it.. alot of times the frame had the holes for the motor mounts for other engines already drilled.. if it was a nonstandard bolt pattern then the trans will be hard to mate to a new engine..

most HOA's dont like busses or RV's and have written rules against it.. I rent storage spots for mine and that worls out well... not sure how you would fair with an HOA and trying to swap a new engine into it..

most states prohibit yellow but im not reading of any people in this forum getting stopped for a yellow bus before they get it painted.. and some people's busses are yellow for a long time..

For the price of the engine repairs a good running bus could easily be found.

Good luck!

That's *Probably* the old 305 V6 engine (or one of it's brothers). Not one of GM's best engines, and these days, darn near impossible to find parts for. Sure, parts exist, but if/when you break down in the middle of nowhere, you'll be on the roadside for a few days awaiting parts. That said, it is my understanding any of the usual V8 engines will bolt right in its place. You can consider a typical 350 or one of the truck/bus 366 engines.

I won't get into your HOA issues, as far as paint, sure, it's not uncommon to brush paint a bus.

an RV-Cammed 350 will run that bus right dwn the road.. keep in mind though you wither need to trust and buy a used one, buy a crate motoe or build one... and an intake and a carb, distributor.. have exhaust made for it etc..

its likely not a cheap endeavor..

I would agree it most likely is the big block 60* V-6 from GMC.

If it is, it will have the spark plugs in the valley between the intake runners. They came in 305, 351, 379, 401, and 478 cubic inches. The 304 was usually found in GMC light duty trucks with the larger ones going into medium duty trucks and buses.

The diesel version of this engine was known as the Toroflow. The only difference was instead of spark plugs, distributor, and a carb it had injectors and a Bosch distributor style injection pump. As bad as the gas engines were, the diesel version was even worse.

If it is one of those engines take it out and use it as an anchor.

On their best day they never could get balanced correctly and would shake themselves to pieces. They tended to run hot so cooling was an issue. They were designed with the V in order to get good high end HP of a V-8 and a long stroke to get good low end torque like an I-6. Unfortunately it didn't have either. The power band was extremely narrow. Running it faster really didn't get you going faster but it did make a lot more noise doing it. Lugging it down very far and it would just quit. On the downhill you had to watch your manifold vacuum or you risked the chance of sucking out the head gaskets. To top it all off it was a very thirsty engine.

A perfect swap candidate would be a Tonawanda 366 high deck big block GM truck engine. The 454 would not be a good candidate for a swap. A small block on paper looks really good but in a bus it just doesn't have enough torque and HP. It is sort of like the difference between a 5.9L/ISB and an 8.3L/ISC--not a big difference on paper but a huge difference out on the road.

im thinking a 350 would handle that little 24 PASS superior fairly well.. finding a 366 in good shape these days and getting parts for it seems pricey... if it were a full size us id definitely not run a 350 in it.. but a shortie (5 or 6 row) superior id run an RV cammed 350 all day...
