Thread: 81 Malibu SBC HEI Upgrade

  1. #1

    Default 81 Malibu SBC HEI Upgrade

    Hi, I have an 1981 Malibu with a SBC. Right now, I have an HEI distributor from eBay.
    I see people going HEI and also going with the GM small cap distributor.

    I'm looking for part number, so I'll buy the right parts. Here's what I have:
    A1 Cardone 84-1830 Distributor
    Holley 558-304 Ignition Adapter

    And could someone recommend a coil to me. Is that all I need to replace the
    HEI system I have, so I can have the Terminator control the timing? Thanks.

    Also, do I need a Holley 554-120 MAP sensor, or does the regulator that came with the Holley fuel kit take care of that?

    Will you also be using an MSD CD ignition box with that GM distributor?
    See figure 23 & 24, on page 17 of the Terminator EFI Manual (Link).

    Also, do I need a Holley 554-120 MAP sensor...
    No, the Terminator throttle body is equipped with a MAP sensor.
    You really need to stop & read the Terminator EFI Manual (Link).

    ...or does the regulator that came with the Holley fuel kit take care of that?
    The fuel pressure regulator has nothing to do with the MAP sensor.
    May God's grace bless you in the Lord Jesus Christ.

    Thanks for the reply; and no CD box, unless you recommend it.

    Actually, I now always recommend a CD ignition box (LINK) with a distributor. They're well built, reliable (especially the digital models), and the greater spark energy is beneficial for starting, smooth idling, lean cruise & possible rich WOT conditions. Meaning sometimes the "tune" isn't always perfect, and these things are never really a disadvantage. The MSD 6201/62013 Digital 6A CDI box & their 8253 HVC-2 coil are a great match. Also, the CDI box fires the coil and takes the load off of the ignition module. (The ignition module just triggers the CDI box.) Conversely, multiple coil ignitions systems (DIS, CNP, COP, etc.) don't use CD ignition boxes.
    May God's grace bless you in the Lord Jesus Christ.

    OK, cool. Thanks for the help, really appreciated. Also, I can't find the white wire in the manual. The one in the loose wires that also has the green fuel pump wire.

    The GM small cap HEI distributor/CD ignition box application, doesn't use the Holley "Points Output" loose white wire.
    Again, see figure 24, on page 17 of the Terminator EFI Manual (Link). Stop & read the Terminator EFI Manual (LINK).

    The one [white wire] in the loose wires that also has the green fuel pump wire.
    It doesn't exist in the Terminator EFI main wire harness. It must be added for other CDI box applications.
    The earlier Terminator EFI wiring harnesses didn't have the "Points Output" loose white wire. It does now.

    Yes, that's the GM small cap HEI computer controlled distributor that most Chevy owners use.
