@douro20 The first American V8's where the caddy Fklatheads first made in all 1914 Caddy's . In 1936 they improved them vastly. The last one was made in 1948 in all Caddy's. Same engine as in the Tanks in WW 2 but no hose outlet on the Water pump for a heater connection. Many crate ( L head was the proper name for Flatheads ) Flathead caddy's where sold in the early 50's after the war as they where not needed in tanks anymore. The 1949 Overhead high compression then was out with 10 more HP.
@greezeyD One piece block, only the early ones in the pre 1936 where two piece blocks, all 1936 to 1948 Flat head (L head) caddy's where modern one piece Blocks. One water pump. Ford and Merc flatheads had two pumps one on each side. I have had both engines over the years. They sound great with Glass packs.
Yes they used two of them and the Caddy hydramaticautomatic trans. in the tanks but they where made to go only forward. Many years ago a Friend of mine bought a crate caddy Flathead made for the tanks with the trans but it only had forward gears! I had a 1948 caddy the last flathead V8 they made and also a 1946, same engine. Great motor and was 346 Cubic inches, hydralic lifters and 150 HP with l;ots of low end power. 7 quarts of oil without the filter alone! much smoother then the 49 OHV V8
I love these old caddies. I had a '40 cad v8 in my 24 dodge roadster, i just loved all the idiots thinking it was a ford flathead in a model A. I love how ignorant people are, they barely look similar.
any truth to the rumor that a caddy v8 like this is a 2 piece block? i think i heard of it from a book, saying the cost to solid cast an engine block at the time was horrendous, and the dirty thirties didnt leave alot of experimentation budget.
Heres the deal with pouring gasoline into the carb. It is THE SIMPLEST AND EASIEST WAY to prime a carbeurator. That being said, typically you just pour in about a cup, start the engine, and when it stops, repeat the process until the carb is primed. It is not the safest thing to do to continually pour while the engine is turning over as a backfire can hurt you. Another method is to saturate the air filter with ether, and put that on there while you turn it over.
Pouring gasoline into a carb is one of the stupidest things to do. I know two people who have had skin grafts because of doing this and having the motor backfire. Just do it right and rebuild the carb. MUCH safer
Very cool! The Caddy flattie would be my choice to mod, not only because of the big displacement, but mostly because, unlike the Ford, the exhaust tract is NOT between the 2 center cylinders and NOT thru the coolant.
My step-uncle gave me a flathead cadillac just like this, and it's been sitting out since the 60s or 70s. I love the way these engines look and sound.
ewwww..I was just waitin' for that carb to backfire and scorch a face or hand. I wanted to lean away from my computer screen even! Other than that......how cool is it to have an ancient Caddy flathead in your possession? Sounds pretty darn good too.
looks kinda rough but she sounds nice, good to see old engines like this one here being ran!

I suppose an aftermarket electric fuel pump would prime things nicely.
But, not a modern one as 50 psi or so may be too much.

shouldnt backfire unless your ignition timing is off or possible valve lash issues.

I would not try this inside a garage. You just might burn the house down.

This was Cadillac's first V8; it only produces 70hp, but a massive amount of torque. It would be an excellent engine for a tractor.
