This HD6 tri-carburettor set uses three SU HD6 units configured for high-capacity induction on modified Austin Healey 3000 Mk II engines. Though not factory-original, this conversion has historical precedent on competition cars and is widely adopted in period-style restorations.
Primarily used as a performance upgrade on 3000 Mk?II cars or custom builds based on BN7, BT7 or early BJ7 platforms. Requires matched inlet manifold and throttle linkage designed for triple HD6 use.
Rebuilds can be done via individual HD6 service kits per carburettor for accurate sealing and fuel metering.
