Long Tube Headers For Ford F-100 F-150 (1965-1974) Black

Unleash the FE Beast: Long Tube Headers for 1965-1974 Ford F-Series FE Big Blocks

Who Is This For? Designed specifically for classic Ford F-100, F-150, and F-250 2WD owners running the legendary Ford FE-Series Big Block (352-428) who want to restore lost performance and achieve that iconic deep V8 rumble.

The FE Exhaust Bottleneck: Your Ford FE-Series engine is a powerhouse, but it’s currently gasping for air through restrictive, heavy cast-iron log manifolds. You step on the gas to pull a load or merge onto the highway, and the engine feels sluggish, choked by backpressure. This “iron lung” setup not only kills your horsepower but also traps excessive heat against your cylinder heads, leading to decreased efficiency and a muted exhaust note that doesn’t do the Big Block justice.

The Engineering Solution: We engineered these Long Tube Headers to completely replace the factory restriction with high-flow 1-3/4" mandrel-bent tubing. By using a 3" formed collector and precision-guided primaries, these headers create a scavenging effect that pulls exhaust gases out of the combustion chamber faster than stock manifolds ever could. This results in an immediate increase in torque and a significant bump in throttle response across the entire RPM range.

The Comparative Edge: Why This Beats the Competition

• Maximum Scavenging: Unlike “shorty” headers or universal kits that offer marginal gains, our long-tube design is tuned for the specific firing order of the FE Big Block to maximize exhaust velocity.
• Leak-Free Architecture: Constructed with 5/16" heavy-duty flanges and O-ringed port seals, providing a superior mating surface compared to thin-flanged aftermarket alternatives that frequently warp and leak.
• Engineered Fitment: This isn’t a “make it fit” universal part. It is specifically designed for 2WD Ford F-Series chassis, including clearance considerations for the FE engine’s unique port geometry.

Technical Specifications & Factory Ratings

Compatibility & OEM Reference

Fits the Following Vehicles:

• 1965-1974 Ford F-100 2WD
• 1965-1974 Ford F-150 2WD
• 1965-1974 Ford F-250 2WD

Installation & Fitment Notes:

• Transmission: On some C-6 automatic models, it may be necessary to bend the linkage arm (1/2" to 3/4") toward the transmission and adjust at the steering column for proper clearance.
• Fuel Tanks: Will not fit 1968-1972 Camper Special models with specific gas tank configurations.
• Break-In Procedure: These headers feature a high-heat resistant black paint. Do NOT break in a new engine with these headers; use old manifolds for initial start-up to prevent heat damage during the curing process.
• Emissions: Stock exhaust must be modified if retaining catalytic converters.
