V8 4-Barrel Carburettor and Inlet Manifold. Direct replacement for the twin Stromberg or SU carbs fitted to the Rover V8. Calibrated to work perfectly on the 3.5 and 3.9 engines, this kit is the most complete on the market and features a Webcon modified Weber four- barrel 500 CFM carburettor with intake manifold, air filter, and all nuts, bolts washers, gaskets and hoses needed. Adds up to 20 BHP at the wheels and transforms the driveability and economy. Offers excellent starting when either hot or cold, and the engine is simply superbly smooth as indeed a V8 should be.
