    As long as you have a square flange manifold flange or adapted to square flange you can use the Holley Sniper of the FiTech EFI systems.

    Does it work with turbo (single mount) and what intake manifold do you suggest for a sbc 305?

    Asked by: Sankanyeah
    You can use it, however you will need special software for boost downloaded from holley.com - the intake can be http://www.jegs.com/i/JEGS-Performance-Products/555/513000/10002/-1 depending on the year of the engine.

    Will this kit work with open headers?

    I have heard that a spacer helps some potential issues with dual plane intakes. Engine Masters some what confirmed this... thoughts? Is the spacer theory plausable?

    Asked by: Jacinto95
    Each application is different. Many will benefit from the use of a spacer, it will be trial and error or you can check it on a dyno for your application.

    What else is required to use this? Do you just simply bill this up and go or are there other parts requires I already have a electric Holley fuel pump btw this is on a small block 350

    Asked by: Kabjr85
    You will also need a fuel delivery system, take a look at 550-516K this includes fuel delivery with the unit.
