Experience the Pinnacle of Performance: Our Exclusive Aluminium Engines

We pride ourselves on offering the highest specification engines available, and our aluminium engines stand at the top of this list. These rare engines, originally produced in limited numbers, are now available to our customers thanks to the expertise and dedication of our founder, John Chatham.

John Chatham’s acquisition of an original aluminium engine set the stage for a remarkable achievement. Leveraging our extensive experience and knowledge, we’ve meticulously reproduced this engine to meet modern standards, making it accessible to today’s drivers who seek the ultimate in high-performance driving.

The aluminium engine offers several distinct advantages over traditional cast iron models. Its lighter weight reduces the load on the front end of the car, leading to enhanced responsiveness and superior handling. This makes it ideal for high-speed cornering on racing circuits and for maximizing overall performance. By choosing our aluminium engine, you’re not just investing in a piece of engineering excellence— you’re also ensuring an exhilarating driving experience that combines classic charm with cutting-edge performance.

Today’s motorists can now experience the thrill of a Healey as never before, with an engine that offers exceptional performance and handling. At John Chatham Classics, we’re excited to bring this unique opportunity to a new generation of enthusiasts.

Servicing & Maintenance

I purchased my Austin Healey 3000 from John Chatham Cars (JCC) in 1999. I am still the proud owner of the car. JCC have looked after the car throughout my ownership. The work carried out by JCC included a total rebuild in 2008, I could not have been more pleased with the result of that rebuild. All works by JCC have been carried out efficiently and within an agreed time scale. John, Jack and all the staff at JCC are always available for friendly and helpful advice.
