About Classic Powertrain
Our History
Classic Powertrain was established by Steve Kenney, driven by his love for classic engines and determination to provide high-quality, affordable engine services to the UK classic car and motorsport community. With over 30 years of experience, Steve has worked on some of the most iconic engines in automotive history. His expertise span a range of engine types, from classic marques like MG, Triumph, Austin, Jaguar, and Land Rover, to high performance drag racing engines. Steve has a long history building hot-rod and competition V8s from Ford, Chevrolet, and Mopar, but he can turn his expertise to most engines, including inboard marine engines, agricultural engines, motorcycle engines, and generator / stationary engines. If it can fit on a pallet and transport to our workshop, Steve can rebuild it!
