Crawling a yard today and found this.. I'm intrigued..
Damn good boat anchor !!!!!
Looks like a Caddy V8 from the old days...
Coffee table base.
Yup, its a Caddy motor, I think some WW2 era tanks used them too.
Your next project!!
This is a 46 Caddy V8-
Hot Rodded Caddy note same front mount-
Bore and Stroke: 3-1/2 x 4-1/2
Piston displacement, Cubic Inches: 346.0
Compression ratio: 7.25
Maximum Brake Horsepower: 150 @ 3400 RPM
Maximum Torque Lbs.Ft. @ RPM: 260 @ 1700 RPM
Cad flathead V8 - the 'other' flathead.
Great hot rod material, but a bit on the heavy side at around 800-900 pounds if I'm not mistaken.
Replaced in 1949 by the famous 331 OHV V8, 160 HP and nearly 200 pounds lighter.
Interesting "galvanized water pipe" used for a crossover, and welded in place. I thought flathead Caddy V-8 also, not that I've ever seen one to compare it to. Did anyone with the yard know what it was? I am Butch/56sedandelivery.
I don't think caddy but for some reason I'm thinking Cord..
After comparing the Caddy flathead pics posted and the boneyard lump I'd have to agree that it's definitely not a Cad engine sitting there in rusty silence....
I think it may be from a Brit car, Oakland, which is something like a lasalle?
I have to agree, still want to know what it is, though.
it would be nice to have another picture from the side. The Lycoming flathead V8 used in the Cord had heads at more of a vertical position. In between a Ford flathead and a flathead six on inline eight.
Oakland was a GM product. For runner to the Pontiac I Believe. LaSalle was GM also. I don't believe that motor is from either.
The only pic I could find of the exact motor with concave heads was in a 31 Oakland.
I scored both complete motors for 100 bucks..
I think this is it too.. 32 Pontiac.
Nice save! You are going to be suprised when you see the valve layout. They ran one of these in the INDY 500 in 1931 or 1932. I sold one to a guy who was building a replica. Bob
neat! I didn't know Pontiac had a V8 back then
From what I can find online, Oakland and Pontiac shared the V8 in question during that time period.
Would love to know the specs on the crankshaft- looking for something beefier for my '28 chevy 4
Dick: Oakland became Pontiac around then didn't it? Tim
They did drop Oakland and continued with Pontiac because Pontiac was outselling Oakland.
Funny how a Google search turns up an old photo of an Oakland V8 that was on an old HAMB post years ago. Bob
I'd need to see the heads, but I think those are 'slot' valves.
Sometimes referred to as 'semi-overhead'.
I love old tech...
Learn something new everyday.... Cool looking motors now where does one find a spare transmission to hook to it? Or......fab a adapter?
I love the hamb. Learn something new every time I log on.

GM bought Oakland in 30 or 31 and merged it with Pontiac. Pontiac used an Oakland flathead V8 [with a few minor changes] in some of their 32 cars...in 33 Pontiac came out with their own flathead straight 8 engine.
There was a primo 32 Pontiac V/8 sedan for sale locally and I could have scored it for 9 grand....passed to buy something else. Had a nice V/8 rumble to it as a totally stock 32 Pontiac...
