In 2026, the Ford 5.4-Liter SVT V8—specifically the supercharged version found in the 2007–2012 Shelby GT500—is a legendary “iron-block” powerhouse. Paired with the Tremec TR-6060 6-speed manual, it represents one of the most robust and tunable drivelines Ford ever produced.

Listing Details

• Ford Mustang Shelby GT500 Engine
• Supercharged 5.4-Liter V8
• Eaton Supercharger
• Ancillary Components

1. Technical Profile: The “Condor” Engine

• Engine Type: 5.4L DOHC 32-Valve V8.

• Induction: Roots-style Eaton Supercharger (early models) or TVS Supercharger (2011–2012).

• Block Material: * 2007–2010: Iron Block (extremely heavy but virtually indestructible).

  • 2011–2012: Aluminum Block (Plasma Transferred Wire Arc technology; significantly lighter).

• Transmission: Tremec TR-6060. This is a heavy-duty 6-speed manual capable of handling 600+ lb-ft of torque in stock form.

2. 2026 Market Valuation (Estimated USD)

With the rise of “modern classics,” these driveline pallets are highly sought after for restomods, particularly for F-100 truck swaps and Fox Body Mustangs.

3. Critical “2026 Status” Checklist

If you are buying or maintaining this setup, pay attention to these known areas:

• The 2011–2012 Bearing Issue: Some of the aluminum-block 5.4L engines experienced issues with main bearings if pushed to high RPMs without proper warm-up. Check for metal shavings in the oil filter.

• Supercharger Coupler: Over time, the isolator/coupler in the Eaton blower can wear out, causing a “clunking” or “rattling” sound at idle. By 2026, most owners have upgraded to a solid coupler.

• Clutch Life: The factory twin-disc clutch in the early GT500s was prone to heat-soak and “chatter.” If the transmission is out, it is highly recommended to upgrade to a McLeod RST or RXT twin-disc system.

• Harmonic Balancer: The stock balancers are known to wobble or separate at higher mileage. An Innovators West or ATI balancer is the standard 2026 “bulletproofing” fix.

4. Swap Considerations

• Height & Width: The 5.4L SVT is a “Tall Deck” modular engine. It is physically much taller and wider than a Coyote 5.0L. It will not fit in a 1965–1970 Mustang without removing the shock towers or using a custom K-member.

• Electronics: Running this in a swap usually requires the Ford Performance Control Pack (which is getting harder to find for the 5.4L) or a standalone like Holley Terminator X Max.

• Hydraulic Clutch: The TR-6060 uses a hydraulic throw-out bearing. If you’re putting this in an older car, you’ll need a hydraulic master cylinder conversion for your clutch pedal.

5. Tuning Potential

In 2026, the 5.4L remains a “bang-for-your-buck” king.

• A simple pulley swap, fuel injector upgrade, and a custom tune can easily take an iron-block 5.4L from 500 hp to 700+ hp at the crank without opening the engine
