The Ferrari Tipo 047 is a 2,936 cc, 90° V8 naturally aspirated petrol engine produced between 1985 and 1989. It features dual overhead camshafts (DOHC), four valves per cylinder, and Bosch K-Jetronic mechanical fuel injection, delivering 239 kW (325 PS) at 7,700 rpm and 300 Nm of torque. Developed for the 308 GTB/GTS Quattrovalvole platform, the Tipo 047 replaced the two-valve F105A with a high-revving four-valve head to improve breathing and power output.
Fitted to the Ferrari 308 QV and 328 GTB/GTS, this engine was engineered for balanced mid-engined performance and everyday usability in road-going sports cars. Its design prioritised smooth power delivery and throttle response, with a dry-sump lubrication system ensuring oil control during spirited driving. Emissions compliance was achieved through secondary air injection and catalytic converters, allowing Euro 1 certification for European market models.
One documented engineering concern is cylinder head cracking, particularly around the exhaust ports, due to thermal stress in high-performance use. This issue, highlighted in Ferrari Service Information Bulletin 308-SIB-06, affects early 308 QV units with thin-cast cylinder heads. In 1986, Ferrari introduced reinforced head castings and revised cooling passages, significantly reducing failure incidence in the 328 series, as confirmed in factory service documentation.
Production years 1985–1989 meet Euro 1 standards (VCA UK Type Approval #VCA/FER/6612).
The Ferrari Tipo 047 is a 2,936 cc 90° V8 naturally aspirated engine engineered for mid-engined road cars (1985–1989). It combines DOHC four-valve architecture with mechanical fuel injection and dry-sump lubrication to deliver high-RPM power delivery and reliable track use. Designed to meet early European emissions standards, it balances performance with road legality.

The K-Jetronic fuel system provides predictable throttle response but requires precise mechanical adjustment to maintain optimal mixture. SAE 10W-60 mineral oil is required for high-temperature stability and bearing protection, with oil changes recommended every 6,000 km or annually. The timing belt must be replaced every 60,000 km or 5 years to prevent catastrophic failure. Cylinder head cracking risk is elevated in early 308 QV models; post-1986 328 units feature reinforced castings. Dry-sump integrity must be verified during service to prevent oil starvation. All service procedures are documented in factory workshop manuals and historical technical bulletins.
Oil Specs: Requires SAE 10W-60 mineral oil meeting FIA Appendix J standards. Not compatible with synthetic oils due to compatibility with original seals and oil pump.
Emissions: Euro 1 certification applies to all 1985–1989 models (VCA Type Approval #VCA/FER/6612). Secondary air injection required for cold-start emissions control.
Power Ratings: Measured under FIA Appendix J standards. Output varies with air flow meter calibration and ignition timing (Ferrari TIS Doc. T047-PWR-110).

The Ferrari Tipo 047 was used across Ferrari's mid-engined V8 platforms with transverse mid-engine mounting and no emissions exemptions. This engine received platform-specific calibrations—higher compression in the 308 QV and improved cooling in the 328-and from 1986 the 328 series adopted reinforced cylinder heads and revised intake manifolds, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine serial number stamped on the rear of the engine block near the gearbox mounting flange (Ferrari TIS T047-ID-05). The prefix "F105CB*" indicates Tipo 047 configuration. Visually, the engine features a 90° V8 with black valve covers, Bosch K-Jetronic fuel distributor on the intake plenum, and dry-sump reservoir on the right side. Critical differentiation from earlier F105A: the Tipo 047 uses a four-valve head and timing belt (vs. chain). Service parts require chassis number verification—each unit was hand-built with non-interchangeable components per factory records (Ferrari SIB 308-SIB-06).
The Tipo 047's primary reliability risk is cylinder head cracking, with elevated incidence in early 308 QV models used in sustained high-RPM operation. Internal Ferrari service reports from 1987 noted multiple failures in road-driven examples with inadequate cooling maintenance, while VCA inspection records show air injection system faults contribute to a portion of emissions-related MOT failures. Extended high-load operation without proper warm-up increases thermal stress, making coolant system integrity and timing belt maintenance critical.
