OK I got the crank out ...... does that help? The block and crank are all drilled but there's no place for an oil pump Maybe a shot of the front will help. What do you think that big chunk-0-iron at the top of the block for?
Do you think that may be a GAZ50 or later Russian Jeep engine? They were based on the B Block Ford banger and later converted to OHV before transfer of all tooling etc. to the Chi-Coms. Back in the late 60s a bunch of new Russian Jeep B engines and parts were imported by devious means to the US and sold by several old Ford outlets. Sadly, after some months of investigation in the late 80s the Chi-Coms informed us that the GAZ series engine tooling they had received from the Russians was destroyed when the updates were made to the Chinese military vehicles. So, the wuestions is, can you trust the Chi-Coms...I think not.
I do not know the internal construction of the GAZ other than the project started out as a stock 34 counterbalanced crank B block.
Open jackets with plates look ooold...maincaps and crank look modern. If it's Blutos, it's something pretty esoteric. Dang...looks like half a Wills StClaire...
The interesting part to me is those look like insert bearings. The original arhitecture looks like Model A three main bearing with rear thrust. With the extra two webs being thinner than the "original" three. Hence my inclination is a beefed A or B design for tractor or military use. I think that extra boss is to mount a water pump and I of course that bottom end is fully pressurized for oil. Water jacket plate looks to be an additional measure to increase cooling since it looks from the picture that the barrels are surrounded by a first layer water jacket. The plate I guess encloses another water layer/chamber increasing cooling capacity.
No valves or cam but obviously a place where they one were. I think the theory of this being basic Ford architecture is on target with some OHC type valve arrangement.
The bore centers kinda look "A" as well. Guess I'm gonna feel like a real dope when you tell us what this really is. :- )
Obviously based on something with low cam, but obviously cast with much of that architecture deleted...Open jackets suggest less sophisticated foundry... Frontenac.
Staring, staring...lower flange is starting to look like A-B with side timing cover cast in...and look at the undrilled UPPER casting pad on the rear...that is suspiciously Fordlike...wish I were at home with an engine block to compare. Bunch of upper surface holes seem to match up to A-B too... Dang, I'm starting to think this might well be designed to live where there once was a B block...
I wrote my name on the side so the guy in the scrap yard I got it from didn't sell it to someone else Man I rode my bicycle home as fast as I could and got the truck. This things heavy!
after looking around it seems that hal made steel blocks as well. hal indy/big birtha blocks were steel, seemingly copies of fords. possible?? haven't seen anything that includes the mount on the side that this block has though.....
OK...found better photos to scrutinize. I see complete match (as much as a match can be made without dimensions) of the bolt pattern and other holes around cylinder tops to a Model B...bolts on right of engine shown, around where valves would be if flathead, I can't see. Maybe not drilled. Pan area seems to correspond...and lookit the water inlet pad, as well as that upper rear pad. Gotta be a based on bolt patterns and dimensions of '28-34 Ford.
Without normal cam or any holes for pump/ignition, the side mount pad would be needed to carry a side drive off of the front cover for ignition, probably water pump, and oil pump would have to be either on side or off of front too...
