Edelbrock Installation Note INSTALLATION NOTE: It may be necessary to plenum match the carb flange of the intake manifold to eliminate a positive step created by the oversized bores of the #3888, 3988 & 38883 throttle bodies.

These 90mm single bore throttle bodies are designed specifically for use with our Pro-Flo XT EFI manifolds and Victor EFI intake elbows. They are ideal for high performance street, race and custom EFI system installations. Available satin, polished or black powder coat finish. Universal Pro-Flo XT Throttle Bodies have provisions for either LS1 or LS2 mounting bolt patterns. They use a LS1 style TPS and 4-wire stepper motor IAC. They include an idle bleed screw to offer better idle control than other 90mm throttle bodies on the market. The bleed screw can be used to create a base amount of idle air flow instead of using throttle tip-in, leaving the TPS signal unaffected. Features a 4.5" diameter inlet flange and is ideal for use with Edelbrock Pro-Flo XT intake manifolds #7136, #71363, #7137, #71373, #7139, #71393, #7144 and #71443. Small-block Ford Pro-Flo XT throttle bodies are for use with our Intake Elbows or Pro-Flo XT intake manifolds #7128 and #71283. Includes a Ford style TPS and provisions for a Ford style IAC motor, OEM or Edelbrock #36017. Uses a standard Ford 5.0L mounting bolt pattern and has a 4.0" diameter inlet flange.
