    The Holley GM 2-bbl Throttle bodies have been designed with all the relevant emmisions provisions, electrical hook-ups and are replacements of the original equipment throttle bodies for the applications shown.

    Features:
  • Direct replacements for OE units*
  • Increase HP & torque up to 25%
  • 2" throttle bores provide 42% more area than stock
  • Compatible with OE plug-ins for a quick installation

    *These Holley throttle bodies are considered equivalent to original equipment so they're 50-state legal and do not require a CARB Executive Order number.

    *670 CFM units may require intake porting or throttle body spacer 555-15404 and fuel line extensions 555-15411.

  • 502-9 - Holley GM 2-bbl Throttle Bodies is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Holly TBI Easy to install, only took about 15 mins Very easy to install. Some people had talked about having to bend the EGR bracket but mine was already out of the way. Seems to have added some power over 300 RPM. Much smoother Idell and transition is good as well. I also added the Flowtech Shorty Headers that were a direct fit and seems to have helped also

    I have this throttle body but I'm looking for one to give me more performance, do you have any?

    Asked by: Jonathank92
    This is the most you can do with the TBI setup. You would need to look into a new intake manifold and a different fuel management product.
