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.

Great looking Blazer and not too heavy for Spring/Summer/Fall wear
Size: X-Large, Color: Khaki, Size: X-Large, Color: Khaki
This is a great looking light to mid-weight blazer. I love the quality and stitching of this blazer which can't be beat for this price. The color is spot on as shown on Amazon, what you see is what you get. The cut fits me perfectly and I like the way it feels when wearing it. There is a faux pocket square in white in the breast pocket, which I am unsure if it is removeable. Either way still looks great and I would definitely recommend. The only - is that if it gets a wrinkle, it is very hard to get it out. You need to steam it for a long time before the wrinkle is removed.

Darker than advertized
Size: Medium, Color: Grey, Size: Medium, Color: Grey
The grey is much darker than advertised. Additionally, jacket came with two buttons and not one as advertised. I ordered a Medium and it fits a little big. No inside pocket, which isn't the worst, but I really like inside pockets.
