Webcon has offered a Weber manifold for the Rover V8 engine for some time. With two carburettors positioned on each cylinder head, this has sometimes proved a little too high for some applications. Now, Webcon has revised the design and positioned four Weber IDF carburettors in a line along the the manifold between the heads, much like the early Aston Martin V8, creating an overall lower profile.

The height of the assembly from the top of the intake port to the top flange of the carburettors is 150mm. The stock air horns are 56mm giving an overall height of 206mm. This can be reduced by 40mm by using 16mm air horns and low profile emulsion tube holders.


  • Venturi: 36mm

  • Air Corrector: 175

The Rover V8 Weber 44IDF Inline Carburettors in the kit are supplied with the “starting point” calibration above which will allow the engine to start and run. To achieve maximum power, driveability and efficiency, we recommend that you have the carburettors professionally set up on a rolling road. This is a service we can offer on our in house Superflow AD30 2 wheel drive chassis dyno. Please Contact Us¬†for more information.

This carburettor set is made to order so the lead times can vary. Estimated dispatch time within 20 working days, please contact us if a more accurate lead time is required.
