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 lb-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.

This Cadillac 500 build puts out a jaw dropping 806 horsepower and 747 lb-ft of torque. It powers a Buick Regal that nips at 200 mph in the standing mile.
