    Default 455 olds intake question.

    I am replacing the stock intake manifold on my 455.....what is with the big metal pan/slash guard under the manifold,between the manifold and the pushrods? I've only worked on BBC's and have never seen this before. Is it needed?

    If you are going to an aftermarket manifold, DO NOT use that tray.

    They refer to it as the turkey tray, it also acts as the intake gasket. If going with an aftermarket intake you can get aftermarket intake gaskets that are way better than the stock tray set up.

    YOu may have to run heat riser block offs...and depending on the setup a gasket on the front/rear of the manifold or a nice thick bead of silicone.

    It's nick named the "turkey tray" ditch it, and run the paper type such as Mr. Gasket..... Use exhaust block off's from Edelbrock, the type that go into the head, the sheet style will burn thru, and burn/crack the intake.

    Felpro #1356
    Mr.Gasket #404 or a thicker version #5846

    ... don't even think about trying to use the metal tray for marine use

    Sleekcraft137,

    I use these 2 items. The oil splashes up against the underside of the intake manifold and burns.

    The splash tray also helps keep oil in the bottem end where it is needed imho.

    They are around $39.00 per item and can be found at Mondello's or Dick Miller Racing.

    You will also need a piece of 6mm thick cork to make new gaskets to seal the front and back of the manifold at the dist and waterpump side.

    The seals you get with the gaskets never seals properly.

    Wikus, I haven't used any gaskets on any manifold ends in decades. A generous bead of silicone, allowed to squeeze out, has sealed BBC, SBC, and OBB without any issues. Once the RTV starts to kick a dish soaped finger will detail the squeeze out to a nice full negative radius..... If an engine blows it out, chances are it would have blown out a gasket as well......(Blow by, internal pan pressure).....Ray
