Had a chance to pull a bearing cap off and check other info. The bearing does have a positioning tab, so I'm good with the 460M bearings. Block casting number is 3835911 and the identification number next to the distributor is 1744C. Pics attached.
Thanks,

Mark,
Just a follow-up after seeing your info on the block "casting number" and stamped "serial Number".
The casting number "3835911" decodes in my resource book as a '53-'55 235 block car engine backed by a Powerglide transmission. However, that info is based on US made 235 engine resource data. I did come across a comment in a link from an earlier Stovebolt conversation on Canadian 235 identification that listed that casting number as one used for Canadian '53-'55 Chevrolet 235's. It didn't indicate car or truck specifically, nor what transmission may have mated up to it.
As your truck is Canadian made, I can only guestimate that your block is still a '53-'55 configuration which uses the "853M" style main bearing set with the upper half locator pin. Your picture of the upper shell half exposed also helps confirm that. Also, since your truck/engine is Canadian built, the stamped serial number doesn't conform to the US made coding. Perhaps a fellow Canadian Bolter can add some info on the serial number???
Back to the main bearings. I think you meant to say "960M" and not "460M" to mean which bearing set you're "good with", but in this case I think you actually need the "853M" set.
With that in mind, I did some web searching this morning (using the "853M" set and known cross-referenced part numbers for the various manufacturers that made these) and may have found something of interest for you.
Sending that in a PM for further discussion/consideration.
Have a great day!
Dan
PS - Going to be away from my computer for most of the day as I'm heading to a local car/truck show with a nearby Stovebolter. Will check back in later.
