The Webcon 4 barrel replacement carburettor kit is a direct replacement for the twin-stromburg or SU carbs fitted to the Rover V8. Calibrated to work perfectly on the 3.5 and 3.9 engines, the Webcon kit is the most complete on the market and features a Webcon modified Weber 4 barrel 500cfm carburettor, intake manifold, air filter and every single nut, bolt washer, gasket and hose that could possibly be needed. The kit adds up to 20bhp at the wheels and transforms the driveability and economy. Starting becomes instant either hot or cold and with no balance adjustment to worry about with twin carbs, the engine is simply superbly smooth as indeed a V8 should be.
