    LS3 intake manifold

    Can anyone tell me if there is a way to install the intake manifold backwards so the throttle body is towards the back of the engine? If I remove the valley cover it will bolt up no problem. The issue is the oil pressure sending unit boss is in the way of the intake.

    Thanks, Scott

    I know for at least the ls1's they have a kit where it connects in the original place but moves the unit away from the back. I am sure they have something similar.

    you could put a plug in the sending unit hole and relocate the sending unit down I one of the ports by the oil filter.

    just wondering, what's the project?
