    Default Hello from Perth, Western Australia

    Hi Team, I currently putting my 455 back into my 73 Centurion and have 2 issues Im trying to sort.

    Firstly the intake manifold has 2 front and 2 rear holes that look like they either should have caps in them or should have a plug in them and connected somewhere? (to the heater perhaps?

    Secondly, I note previous owners have been doing some electrical work and its looking a bit shabby so would very much appreciate a picture of an electrical diagram for the car.

    Thanks in advance.

    Hi there Eric, Thanks for your message. Another stupid question from me What type of plugs? plastic or metal?

    Looks like I might be all good with the wiring at the moment. Will send you a message if I have an electrical query.

    Cheers

    They should be metal.
    Mine where steel colored but could also be brass with a nickel coating I'm not sure.
    Mine where good so left them in place.
    Are you using your smog pump?
    If not i think you could leave them open.
