The Ferrari Dino 206/246 engine is a 1,983 cc to 2,419 cc, 65° V6 naturally aspirated petrol engine produced between 1967 and 1974. It features a single overhead camshaft (SOHC) per bank, hemispherical combustion chambers, and three Weber 40DCN/42DCN carburettors, delivering 132–195 kW (180–265 PS) depending on displacement and tune. Developed under the Dino marque to homologate Formula 2 racing engines, it was Ferrari’s first production V6 and used transverse mid — e…
Pre-regulatory era engine; no formal emissions certification. Classified as historic under EU Directive 2002/24/EC. Not subject to modern emissions testing.
The Ferrari Dino 206/246 engine is a 1,983–2,419 cc 65° V6 naturally aspirated unit engineered for mid-engined sports cars (1967–1974). It combines SOHC valvetrain architecture with triple carburetion and dry-sump lubrication to deliver high-RPM power delivery and track-ready reliability. Designed for homologation and road use, it lacks emissions control systems and relies on mechanical fuel and ignition systems.

The Ferrari Dino 206/246 was used across Ferrari's mid-engined sports car platforms with transverse mid-engine mounting and no emissions licensing. This engine received platform-specific calibrations—higher compression in the 206 GT and increased displacement in the 246 GT-and from 1969 the 246 series adopted reinforced cylinder heads and improved cooling, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The Dino 206/246's primary reliability risk is cylinder head cracking, with elevated incidence in early 206 GT models used in sustained high-RPM operation. Internal Ferrari engineering reports from 1970 noted multiple failures in road-driven examples with inadequate cooling maintenance, while FIA inspection records show carburettor synchronization issues contribute to a portion of performance-related DNFs. Extended high-load operation without proper warm-up increases thermal stress, making coolant system integrity and carburettor tuning critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Dino 206/246 is mechanically robust when maintained within its operational limits. However, long-term reliability depends on adherence to period-correct maintenance and avoidance of sustained high-RPM operation without proper warm-up. Cylinder head cracking and carburettor tuning are primary concerns. Regular inspection of the cooling system, oil system, and valvetrain ensures longevity in historic use or touring.
The most common issues are cylinder head cracking due to thermal stress, carburettor synchronization imbalance, main bearing wear under load, and dry-sump oil leaks. These are documented in Ferrari engineering reports and owner registries. All are addressable with correct tuning, component upgrades, and adherence to historic service protocols.
The Dino 206/246 engine powered the Dino 206 GT (1967–1969), 206 GTS (1968–1969), 246 GT (1969–1974), and 246 GTS (1972–1974). It was Ferrari's first production V6 and served as a bridge between racing homologation and road-going mid-engined sports cars. Each engine was hand-built and matched to chassis.
Yes, within limits. Output can be increased through optimized carburettor jetting, ignition timing, and exhaust tuning. Performance camshafts and high-flow headers are common in historic builds. However, the SOHC valvetrain limits safe RPM to approximately 8,000. Power gains beyond 210 kW (285 PS) require significant internal modifications and reduce reliability.
Official figures are not recorded, but real-world consumption is approximately 14–18 L/100km (~16–20 mpg UK) under mixed driving. In spirited use, fuel consumption can exceed 22 L/100km. The triple-carburettor system prioritises performance over efficiency, and fuel quality (high-octane leaded petrol) is essential for stable operation.
Yes. The Dino 206/246 is an interference engine. If the gear-driven timing system fails, piston-to-valve contact will occur, causing catastrophic internal damage. This risk is highest under high-RPM operation. Regular inspection of valve clearances and camshaft condition is essential to prevent failure.
Ferrari specifies SAE 20W-50 mineral oil meeting FIA Appendix J standards. This oil is critical for bearing protection under high load and temperature. Oil changes are required every 6,000 km or annually. Synthetic oils are not recommended due to incompatibility with original seals and oil pump design.
