IsolationRide,

I don't know the answer but do have a comment. In my limited knowledge, there is no such thing as a 350 big block. This 'small block' 'big block' thing came on the same train as 'billet' this or that!!

Using the term "350 small block" is akin to saying "female woman". 265's, 283's, 327's and 350's (there are others) ARE small block engines. If you ever find a 350 big block, you better buy it, because it must have slipped through GM quality control.

This is how I remember it!

Stuart

Welcome to Stovebolt.com. It's the place to get your answers. But you only need to post the question in one forum. Posting multiple times won't get better answers.

If it was US manufacture it probably came with a V-6. I don't know about Canadian manufactured busses.

A 40 year old bus could have any engine in it by now. Without some numbers or other ID, it could be a 390 Ford engine for all we know.

Probably a 351 V6. Check out Jolly's site www.6066gmcguy.org for lots of useful GMC V6 info. I think the serial number stamped across the pad or lip on top of the block in front of the intake manifold starts with the C.I.D. It could also be almost any Chevy V8 from that era: 350, 366, 396, etc. Good luck.

How many passengers does it hold? If it has more than 10 seats (20 pass) it would have to have a fairly potent power plant. When full they are pulling a lot of weight.

All mini buses Chevy produced (little bus body on a van chassis) that I have owned including the 80s diesels were 350 blocks with 4 bolt mains. A 35 foot bus built in the late 60s probably would also run a 350.
