⭕ For sale is a WWII Cadillac 346 cubic inch V8 engine, fresh from the crate. This engine is so rare its almost non existant today. I bought it about 10 years ago from a police supply vendor that bought out an old warehouse where this was located. This engine is either surplus or rebuilt. These were used in the M5 tank of WWII vintage. It is sealed well, and is still free to rotate at the crankshaft. Note the position of the holes in the crank pulley. This engine has all the military parts attached, such as the intake, with shaft running through it, special exhaust manifold, and military delco generator. I know of 1 other motor like this that exists. I believe this engine probably is the only one in existance being offered for sale. If you have one of those rare M5 tanks and you need an engine, this would be the ticket. I would imagine it was built to military standards, so it should have a level of quality.
