Video: Hagerty Redline Rebuild — Time-Lapse Cadillac 365 Rebuild

If you’ve followed EngineLabs for any amount of time, you probably know were a sucker for Hagerty’s Redline Rebuild series , where they employ some truly impressive time-lapse videography to capture the rebuild process of their latest engine projects. Some previous projects include a Chevy Stovebolt Six, a Top Fuel engine, a Dodge Demon engine, and of course, a small-block Ford. This time, it was of a venerable Cadillac 365 V8 engine.

In production between 1949 and 1962, the Cadillac 331-series of engines were the manufacturer’s latest and greatest offering, going to an overhead valve design, with shaft rockers, hydraulic lifters, and a skirtless block. In 1956, the displacement was upped to 365 cubic inches via a 4.00-inch bore and a 3.625-inch stroke. With a 10.25: 1 compression ratio, the four-barrel OEM variant made 310 horsepower off the production line, while the Eldorado model, with three two-barrel carbs made 335 horsepower.

This particular example was manufactured in 1957, making it a 64-year-old mill being brought back to life. Anything mechanical that old is going to have some particularly stubborn parts to remove, and in this case, the studs on the exhaust manifolds require some coercion with an acetylene torch which makes for some really cool footage, if nothing else.

The montage not only includes the teardown and rebuild, but also includes all the steps at the machine shop to recondition many of the factory parts, since replacement parts for this engine family are far less common than, say, a small-block Chevrolet. Once all the machining was done, all the exterior surfaces received a coat of Cadillac Blue paint.

After a brain-soothing time-lapse of the engine being reassembled, it is then wheeled to the back of the shop on the run stand to fire up the engine. However, like most things in real life, there’s a bit of a hiccup along the way (which I’m sure you’ve figured out by now, based on the photos in the article). However, it makes for an interesting bit of video, and when all is said and done, the engine looks and runs better than it did in 1957.

Anyone who has ever installed a distributor 180-degrees off knows exactly what is happening here. Luckily, the video team knew it was a possibility and had the slow-motion cameras set up to record what might happen, further proving how awesome Hagerty’s Redline Rebuild production team really is.
