CLEVOR/BOSS
The best of both worlds.
Clevor History & Evolution
The Clevor or Boss engine isn’t a new concept. These engines have been around since the early 1970s, originally using Windsor blocks paired with Cleveland cylinder heads.
Today, we take that classic combination to the next level. By using aftermarket Dart Windsor blocks, strong Cleveland crankshafts, and high-performance 3V Cleveland heads, we bring together the best of both worlds. The result is a powerful, reliable engine that blends Windsor torque with Cleveland top-end performance.
