    Default 1988 4.3 distributor...

    I purchased a 1986 PennYan and according to the numbers on the motor it is a 1988 4.3

    i decided to buy a new cap, rotor, points, plugs and wires for it and using the numbers I had from engine made my purchase.

    After i I removed my cap I see that I have what appears to be a conversion. However Pertronix web site doesn’t show me any parts for the 4.3 engine.

    Im looking for information/part numbers etc for the distributor cap, the rotor, the ignition module piece inside etc so that I can be prepared when the time comes to replace them. Can anyone help identify what I have?

    If your now existing ignition system has been changed to a Pertronix triggering system, it would have been a system for the type/brand of distributor.
    If the distributor is no longer OEM, then you need to identify it.

    Examples:

    Older Prestolite (and Prestolite copies) uses two screws to secure the cap to the housing.
    Older Mallory uses two flip up clamps w/ screws to secure the cap to the housing.

    Is this engine part of an OMC Cobra system? If so the distributor is a mechanical advance Prestolite and you can get the cap and rotor from either BRP, or Sierra. Check on this site using your model number...it will start with either a 434 (4.3 V6, 4bbl carb) or 432 (same engine 2bbl carb) and then there will be a series of letters, the P or M refer to power or manual steering, the rest are just more specific identifers for the model #.
