    Edelbrock Carb Heat Problems?

    I have a 4 barrel Edelbrock on top of Edelbrock Performer manifold (RR 3.9l v8) and face the issue of a very very hot carbie that's causing fuel vapor issues - I think.

    The carbie is way to hot to touch and my fuel economy non - existent. The smell of fuel vapors and unburnt (?) fuel is very evident. The engine runs like a dog and I am worried it will cause a hydraulic lock.

    Its booked into a carbie specialist in 2 weeks for surgery, but thought I would ask the experts here for any insights!

    I am advised that a 1/2 inch Bakelite block that lifts the carby will assist, but i struggle to believe that 1/2 inch will be enough.

    Has anyone else experienced this or have any thoughts?

    At Carbie specialist I will check dizzy and coil to see if they too are contributing.

    Thanks in advance....

    Cant say i had any heat issues on my RRC when i ran a holley, is the t/stat the correct temp ? You could try making a heat shield from alloy sheet and see if that helps.

    The Bakelite insulator will fix it. Also see if you can arrange a cold air intake if you don't already have one, and a cold air duct from the front of the car to blow outside air over the float bowl. Every little bit helps as the actress said to the bishop.

    I had the same problem with V8 falcon and the spacer solved the problem.
    Mine was perculating petrol when hot after turning off the engine too.

    You can get 1 inch

    Get an Edelbrock manifold and a Rochester Quadrajet. A far better carburettor, and readily available from any wrecker.

    Aren't you going to be a bit light on for air cleaner clearance with a 1inch spacer?
    I suppose you can do a body lift.

    Quadrajet is a beautiful carb, the Edelbrock however is a close second/ almost copy.
    I also agree the bakelite spacer should help.

    I had a few issues with warping the top cover on a Quadrajet with an insulator, be very careful how tight it is bolted down IIRC the Edelbrock carb also has 2 of the bolts going through the whole carb down to the manifold.

    Great looking engine/ installation BTW!

    Anyone have a part number for the Edelbrock manifold and can you still buy a suitable new Quadrajet carby ?
