Edelbrock Pro-Flo XT Throttle Bodies

The Edelbrock Pro-Flo XT 90mm single bore throttle bodies are intended for Pro-Flow XT and EFI Victor elbow applications. The LS style has provisions for either LS1 or LS2 mounting bolt patterns and uses LS1 style TPS, IAC and PCV port. The small block Ford version has a Ford 5.0L bolt pattern, includes a Ford style TPS and has the provision for a factory Ford IAC motor. They offer better idle control than other 90mm throttle bodies, because of the addition of an idle bleed screw. By using the bleed screw to create a base amount of idle air flow instead of throttle tip-in, this way the TPS signal is unaffected!
