Pacemaker | 1 3/4" Tri-Y Competition Headers | 351 Windsor Spread Port XR-XY | PH4036 L/R
Pacemaker Tri-Y Competition Headers - 351 Windsor Spread Port Head - PH4036 L/R
Engineered for high-performance small block Ford builds, the Pacemaker PH4036 Competition series headers are designed specifically for the 351 Windsor engine equipped with Spread Port / Dual Bolt Pattern cylinder heads. Unlike standard Windsor headers, these feature a Tri-Y design with large 1¾" (44mm) primary pipes that step into 2" (51mm) secondaries, ultimately flowing into a 3" (76mm) outlet. This configuration is ideal for maximizing mid-range torque and high-end horsepower in classic Falcon and Fairlane models. Whether you are running a period-correct XR-XY or performing an engine swap into later chassis, these Australian-made headers provide the precision fitment and superior flow required for competition-level performance.
Features:
This product offers the following high-performance features:
- Spread Port Compatibility: Designed exclusively for 351 Windsor heads featuring the wider dual bolt pattern.
- Competition Tri-Y Design: Optimized for a broad power band and increased exhaust gas velocity.
- Heavy-Duty Piping: 1¾" (44mm) primary and 2" (51mm) secondary mandrel-bent pipes for maximum flow.
- Large 3" Outlet: 3" (76mm) collectors support high-horsepower engine configurations.
- Broad Fitment Range: Suitable for original XR-XY Falcons and a wide variety of Ford engine swap models.
