One High Performance Crate Engine At A Time

BluePrint Engines® was started 20 years ago in a small garage in central Nebraska. What started as a passion for speed turned into a hobby, then a job, and finally a career. BluePrint’s founder built one engine at a time for his friends and neighbors, and bit by bit his business and reputation grew. Drag racers, circle track racers, and street rodders all got some of the first engines produced by BluePrint Engines. Today the company he founded has produced over 200,000 factory replacement engines for cars and light trucks.
