The 5 Coolest Cars with Cadillac 500 Engines

The Cadillac 500 engine is a rare engine that not many know about. Used throughout the 1970s, it initially debuted with 400 horsepower and 550 lbs-ft of torque — however, those numbers would drop significantly. This 8.2L isn’t commonly used in builds, but when you do find one, it’s a unicorn of a project. Here are the five coolest Cadillac 500 engine builds.

It features a stock crankshaft, Scat 6.750” connecting rods, and JE forged pistons — build specifically for the 13.0:1 compression ratio engine. It also has a sizable camshaft and massive 1,050 cfm Holley carb. This build proves that the 500 is a beast of an engine that can handle tons of power on a stock block and crank.
