A brand new in box Weber/Edelbrock 500 CFM Carburettor . This listing is for the Carb only but we can supply the a complete kit featuring inlet manifold, gaskets, and all the small parts needed to complete the job. Please see our other items.
Why we don't sell The Holly Carbs for Rover V8.
The most affordable upgrade carburettor option was for many years the Holley 390cfm. This carburettor has been used on all capacity Rover V8s, and with extensive fine tuning can eventually provide good fuelling and power for the V8 engine up to 3.9 Litres. However, the problems have always been that it is too large (390cfm) for part throttle economy/torque, and too small for more serious top-end power gains, especially on larger capacity engines. So, unless you are into drag racing, our advice would be to forget it.
Although the Edelbrock is 500 cfm, it is only approx. 200 cfm on part throttle, the additional 300 cfm comes in on the secondary part of the carburettor. The advantage of the Weber is that the secondaries are both vacuum and throttle operated (unlike the Holley which is vacuum only). This has the advantage as sometime the engine is under load (vacuum) however you are only on part throttle and the engine does not need the secondaries open. The result of this in simple terms is that the Weber can provide a smooth power delivery where other carburettors would struggle.
The Weber 500 is better off road
Unlike the Weber, the Holley float bowls are mounted both in front and behind the carburettor, causing fuel starvation and fuel flooding problems when off roading on steeper inclines. The Weber's float bowls are either side of the carburettor, thus almost completely alleviating this type of common problem even when on banks.
Proven time and time again, beyond doubt
In the past ten years of fitting this carburettor, along with supplying to our many hundreds of customers we have achieved a great deal of combined experience in road, off-roading (trailing) and competition use. We have had no reports of issues with flooding or fuel starvation even when traversing steep inclines and faster cornering.
