Thread: MSD 2357 Distributor

  1. #1

    Default MSD 2357 Distributor

    I was wondering if the MSD 2357 distributor is compatible with the Holley HP EFI cam sync & crank signals, so I could use the sequential EFI tuning.

    Don't waste your money, it doesn't have a Hall-Effect crank sensor. Why would you not use the Holley Dual Sync distributor (with two Hall-Effect sensors) that's specifically designed and "plug & play" for Holley EFI?

    FYI: Holley EFI now sells their own Dual Sync Hall-Effect distributors (LINK).
    They're a small cap design, "plug & play" with Holley EFI, and no need for a modified Firing Order.
    The crank & cam sensor signals also provide sequential injection capability (MPFI applications).
    It's "plug & play" (into the 10-pin ignition connector on the EFI Main Harness) and requires a CD
    ignition box (Instructions). The MSD 6201 Digital 6A CDI box & 8253 HVC-2 coil are a great match.
    The MSD CD ignition box is wired as shown in the Holley EFI Wiring Manual:
    http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual - Figure 11, Page 20)
    https://www.youtube.com/watch?v=AM7r-DauCak (Holley EFI Dual Sync Distributor - YouTube Tech Video)
    A blank cap (LINK) is available, if the user decides to convert to Coil-Near-Plug/DIS later (no CDI box).
    Of course, this component can also be used as a crank and/or cam sync/oil pump drive unit.

    The Custom Ignition Parameters (in System Parameters) for the Holley EFI Dual Sync Distributor:
    Ignition Type ............. ― "Custom"
    Crank Sensor Type ..... ― "1 Pulse/Fire"
    Sensor Type .............. ― "Digital Falling"
    Inductive Delay .......... ― "100.0 usec" ( Synchronization info, adjusted per application.)
    Ignition Reference Angle ― "50°" ( Inherent rotor-phasing of this unit.)
    Cam Sensor Type ........ ― "Single Pulse" ( "Not Used" for TBI, unless CNP ignition.)
    Sensor Type .............. ― "Digital Falling"
    Output Setup Type ..... ― "Points Output" ( CDI box ground trigger.)
    Dwell Time ................. ― "2.0 msec" ( Do not set this to 1.5 msec!)

    I was looking for a distributor that has the slip collar on it, to make sure the distributor is in the correct position. But if it doesn't have the Hall-Effect crank sensor, then I guess that answers my question.

    Holley has a BBC Dual Sync Distributor with an adjustable slip collar (LINK). Which engine is this?

    I have a 400 SBC Dart SHP block, AFR heads and a converted LT1 intake. Had trouble getting the distributor to sit all the way down. Fit my previous engine with no problem. GM small cap HEI distributor. Figured I should upgrade since everything else is new. This intake was on my last engine BTW.

    You can machine the flange off the distributor, and MSD Ignition does sell an adjustable slip collar (LINK).
