Thread: N/A SBF Build Component Suggestions

  1. #1

    Default N/A SBF Build Component Suggestions

    Hi everyone. My first post here. Presently building from a clean slate and would like to hear recommendations for some smaller component selection. Details are as follows:
    N/A SBF 412 CI will make 750 HP.
    Hall-Effect Flying Magnet crank trigger and Price Motorsport cam signal.
    GM 4L80E transmission.
    Dominator throttle body and ECU and prefer to run CNP ignition.
    Holley Digital Dash plus CAN Bus gauges.
    Entire electrical system is a clean slate.
    I’m trying to do this vehicle as correctly as possible in all areas.

    My questions are:
    1) I have D514 Delphi coils, are these sufficient or should I step up to the Holley CNP smart coils?
    2) Planning on using either the MSD Super Conductor or Holley EFI plug wires, any real preferences or experiences?
    3) Should I buy a dual terminal type battery to keep a clean power supply? I see mention of this in a Holley training video.
    4) What are the best brand diode protected relays to use? Obviously I’m not keen on damaging my ECU with flyback.
    I’m assuming the Dominator does have some internal protections, but a quality diode type really is still strongly suggested?
    Thanks very much everyone, looking forward to hearing your suggestions. Steve

    Thank you Danny. I already have Holley Hall-Effect crank and Price Motorsport cam sensors. The upgrade to the Holley smart coils in the link is noted, but is it necessary?

    A N/A engine should be fine with the Delphi D514 CNP coils.

    Thanks Danny, I appreciate your assistance. From what I’ve read the MSD Super Conductor wires work well? Diode protected relays are plentiful, are there any Brands of a superior quality that anyone has used?

    Focus on your intake/TB selection. SBFs do not do well with carb intakes converted to EFI I find. Go with an EFI specific intake. Holley Hi-Ram or TFS Box-R are good choices. They usually have good cylinder to cylinder balance compared to a Super Victor and are much easier to tune. I'd prefer the MSD 85061 cam sync plug. It's a very reliable robust unit and is plug & play with Holley. If you decide the Super Victor I prefer a 1:1 TB and be able to open the rear two for idle control. Also, a good spacer helps. Otherwise, you'll have a terrible time with the back two fouling at idle.

    1 Pulse/Fire Flying Magnet crank triggers also work well and tend to be more reliable than 36-1 wheels, but they do lose a lot of resolution. Some people prefer a 12-1 Flying Magnet setup like Hyperaktive or have the magnets built into the balancer. Innovators West and ATI can do this for you.

    For plug wires, I recommend FireCore50 wires and nothing else.

    Dual terminal batteries are great choices for Holley EFI installs. Keep the Holley on its own dedicated terminals. Run everything else off of the other set.

    What do you plan on running the relays with? The Holley EFI units have some flyback protection, they can even PWM small inductive loads directly with no flyback protection. If you're doing a PWM fuel pump, I suggest the Crydom D1D40.

    The other major issue you need to pay attention to is grounds (NOT just "having lots") and the ignition coil wire harnesses. They need to be grounded with the shortest path possible to each head.
