We live in a golden age of automotive performance. Modern technology continues to allow us to push the envelope of what is possible in terms of engine design and output. That being said, many of us in the USA often forget that there are also horsepower fans all over the globe.

We recently came across this video of Australian engine builder Dandy Engines, building an 800-plus hp naturally aspirated windsor engine for a customer. The Aussies love horsepower as much as we do here, and this particular engine was destined to go in a Ford Falcon ute, the modern day Aussie equivalent of the long defunct American Ranchero.

Although it’s built in Australia the list of components that goes into this engine are mostly sourced from US companies. The foundation is a Dart block, housing a Callies crank with 4.25-inch stroke, to spin Oliver connecting rods pushing Diamond Racing 12.5:1 gas ported, and coated slugs. The camshaft comes from Comp Cams, and is a custom 54mm solid roller grind and spins via a Jesel belt drive.

A custom billet oil pump with dual pickups, and a customized Moroso oil pan wrap things up on the bottom end.

Cylinder heads call in another big name in the world of Ford performance, CHI, Kasse. No details were given on exactly which Kasse heads were used, but from the photos we know they have some major flow potential. The engine also received a matching intake from CHI, Kasse as well. Topping things off is a BRE 1150 carburetor.

Dandy strapped this beast to the dyno and fired it up. Once the vacuum pump was online, the 461 cubic inch engine made an impressive 869 hp and 664 ft-lbs of torque, spinning all the way to 7500 rpm.

Checkout the video and watch the guys from Dandy Engines build the beast, and then listen to that sweet small block Ford music, as they make big power with a naturally aspirated engine, the Aussie way.
