About This Engine

The Ford 5.2L Voodoo is the highest revving, naturally aspirated production V8 ever built by an American automaker. Found exclusively in the 2015 to 2020 Shelby GT350 and GT350R, the Voodoo combines a flat plane crankshaft, forged Manley billet steel rods, a 12.0:1 compression ratio, sequential multi port fuel injection, and an 8,250 RPM redline to produce 526 horsepower at 7,500 RPM and 429 lb-ft of torque at 4,750 RPM, all with the throaty wail of a Ferrari V8 fighting an American small block.

The Voodoo shares the basic Modular V8 architecture of the 5.0L Coyote but virtually nothing else. The block has a thicker deck and revised oiling. The crankshaft is a true 180 degree flat plane (similar in design to Ferrari V8s). The connecting rods are Manley billet steel with ARP2000 bolts. The pistons are forged aluminum. The cylinder heads use larger valves and Voodoo specific port and combustion chamber design. The intake manifold is a high RPM tuned plenum. The result is a small block V8 that sounds and revs like nothing else from Detroit.

The Voodoo is found only in the GT350 (wet sump) and GT350R (dry sump on Track Pack cars). Total production was approximately 24,000 units across the GT350 and GT350R combined. After 2020, Ford discontinued the Voodoo entirely; the next 5.2 Mustang engine is the Predator (supercharged, cross plane) used in the GT500.

Signs You Need a Replacement Engine

• Excessive oil consumption beyond 1 quart per 1,000 miles (a known issue on early 2016 units)
• Bottom end knock or rod knock under high RPM load
• Loss of compression on one or more cylinders
• Cylinder wall scoring from over rev or dropped valve
• Connecting rod failure (rare on Manley rods, but possible on track abused units)
• Oil pump failure causing low oil pressure on dry sump GT350R units
• Spark plug fouling or coil pack failure causing misfire

Known Things to Know Before You Buy

• Voodoo is FLAT plane, Predator is CROSS plane: This is the single most common buyer confusion. The 2015 to 2020 GT350 / GT350R uses a Voodoo (flat plane). The 2020 to 2022 GT500 uses a Predator (cross plane, supercharged). They are different engines despite both being 5.2L Ford V8s. Never substitute one for the other.
• 2016 Voodoo oil consumption: Some early 2016 GT350 units had a piston ring break-in issue causing high oil consumption. Ford addressed via TSB 16-0136. Verify any 2016 unit has had the TSB rework.
• Wet sump (GT350) vs dry sump (GT350R Track Pack): The dry sump GT350R version has a separate oil tank, dry sump pump, and revised oil pan. We confirm sump configuration before every order.
• Aluminator XS crate vs factory: Ford Performance offered an Aluminator XS crate version of the Voodoo. It uses different pistons (10.5:1) for forced induction tolerance and is not the same as a factory Voodoo. Specify which you need.
• Cam phaser noise: Some Voodoo units develop a cam phaser tick at idle, similar to the Coyote. We listen for this on every running unit.
• Discontinued production: Ford no longer produces the Voodoo. Used OEM units are the primary supply path for GT350 owners going forward.

Direct factory applications:

The Voodoo was never offered in any other production vehicle. Swap candidates: S550 Mustang chassis (2015 to present), classic Mustang restomod, Cobra replica, kit car. The Voodoo bolts to the Modular V8 bell housing pattern (Tremec TR-3160 6-speed manual is the factory pairing on GT350; the Tremec TR-9070 dual clutch was never offered with Voodoo).

Not a GT350 owner but want a Voodoo for a swap? Call (240) 301-0095 with your project. We confirm bell housing, oil sump plan, harness, and ECU before shipping.

Common Names and Search Terms

Used OEM vs Crate vs Aftermarket Built

A documented used OEM Voodoo from a known donor (low mileage GT350 or GT350R) is the only practical replacement option for most owners since Ford has discontinued the engine. Our Voodoos are compression tested, sump configuration documented, and donor mileage disclosed where available.

A factory crate Voodoo from Ford Performance (M-6007-M52) is rare, special order, and runs $14,000 plus when available. The Aluminator XS crate (FRPP) uses different pistons for forced induction and is not the same as a factory Voodoo replacement.

A built Voodoo from a specialty Ford performance shop typically runs $18,000 to $30,000 plus depending on bottom end specification. Built makes sense for a track focused GT350R or a forced induction project. For most stock GT350 replacements, a verified used OEM unit is the right path.

Condition and Inspection Process

• Compression test across all 8 cylinders, pressure per cylinder recorded
• Visual inspection of block for cracks, cylinder wall scoring, and head bolt thread integrity
• Crankshaft type confirmed FLAT plane (visual on counterweights, casting verification)
• Connecting rod material confirmed Manley billet steel
• Wet sump or dry sump configuration documented
• Cam phaser noise check on running units
• Spark plug condition documented across all 8 cylinders
• Donor model and year confirmed
• 2016 oil consumption TSB rework status disclosed where applicable

Mileage is documented when available from the donor vehicle. Where mileage cannot be verified, we disclose this before shipping.

Buyer Tips, What to Know Before You Order

• Confirm Voodoo, not Predator: This is non negotiable. A Predator has a cross plane crank and a supercharger. A Voodoo has a flat plane crank and is naturally aspirated. The Predator will not bolt to a GT350 chassis correctly and the calibration is incompatible.
• Wet sump or dry sump: Match your car. A GT350R with dry sump cannot use a wet sump Voodoo without converting back. A wet sump GT350 cannot use a dry sump Voodoo without adding the dry sump tank, lines, and pump.
• ECU calibration is year specific. A 2015 Voodoo running a 2020 ECU calibration may run but will not run optimally. Plan for a re flash at your tuner if year mismatched.
• Plan a coil pack and spark plug refresh at install regardless of engine condition. These are wear items.
• 2016 oil consumption: If buying a 2016, verify TSB 16-0136 has been performed (cylinder honing and ring replacement). Without this, expect oil consumption.
