HRS Engine Development (Huub Ritzen Special engines) is a one-man business specialized in building Ford and Chevrolet V8 competition racing engines. Most of the engines built at the HRS Engine Development shop are used in historic racing cars, but some are 350+ HP engines used in high-performance street cars.
At one point, I decided I would stop drag racing myself and instead concentrate on building V8 racing engines. In the meantime, I was still involved in drag racing as an engine builder for show time drag racing in the UK and building engines for the oval track scene as well.
