Edelbrock 3878 - Edelbrock Competition Throttle Bodies

These progressive 4-barrel throttle bodies bolt directly to the standard square-bore or 4500 Series carb mount flanges for competition electronic fuel injection systems based on Edelbrocks Victor Series manifolds. Fully machined by Edelbrock, they are assembled/calibrated by Magneti Marelli USA and include a GM style throttle position sensor (TPS). 350-3878, 350-3879, and 350-3888 include a Delphi/GM idle air control (IAC) motor. Standard style air cleaners (5-1/8" or 4500 series) will fit.
