    3900 crankshaft flange

    Hey guys...I would like to know how far in, or out, the crankshaft flange (that a flywheel or flex plate bolts to) is from the engine block (the surface that a transmission would mate to). Is it true that all 60 degree V6s share this same dimension? I'm having to design a custom flywheel/pressure plate for a project...

    Thanks in advance

        No, maybe someone here has access to an engine and can take a measurement for you, I'm to far away from home. You should probably start with a stock flywheel measurement though instead of a measurement point relative to the flange unless you are using an adaptor plate.
