 Aftermarket & Performance Potential Ford 7.3L Godzilla Engine

• Stock crate engines like Ford Performance M‑6007‑73B deliver the factory 430 hp & assembly/hardware included

• Companies offer beefed-up crate builds:

  • 525 hp with upgraded internals ($15 k+)

  • “Boost-ready” 700 hp packages

  • Supercharged builds hitting 850 + hp or even near 1,000 hp Powers Super Duty trucks and chassis (F‑250 through F‑750, E‑Series vans, motorhome chassis, school buses)

• Reviewers note it’s a durable, simpler gas engine alternative to diesel in large trucks—offering similar power at lower cost and complexity

• Enthusiasts report it’s reliable for the long haul—300K + miles is common with proper maintenance:

 Swaps & Accessory Upgrades

• Holley High‑Mount Accessory Drive Kits (~$700–$2,950) streamline engine swaps, relocating oil pump, alternator, PS/A/C accessories, and improving clearance Engine swap-specific parts from Billet Pro Shop, Weir Racing & Apocalypse Performance include:

  • High-flow billet fuel rails, valve covers, water-pump delete plates, oil cooler adapters, lift plates ($50–$300)

  • Headers from Ultimate Headers for Fox Bodies & Mustangs (MSRP ~$1,400–1,480)

  • Indy Power Products intake manifold boosts RPM power, credited with ~625 hp on a swap

• Cam Phaser Lockout Kits & special socket tools available for those running big cams or locking VVT—handy for consistent high-RPM tuning

 Real-World Ownership & Reliability Ford 7.3L Godzilla Engine

• Owners praise engine’s torque and capability in real-world towing:

• Teething issues with lifters & oil pump tuning appear resolved in 2023+ Godzillas:

• Some early issues with transmissions in 2020-2022 trucks, but more recent models show better reliability .

 Summary & Next Steps

Where do you want to go next? I can help you explore:

1. Parts sourcing and pricing (e.g., Holley kits, intake manifold, headers).

2. Planning a specific build: NA big-cube, boost-ready, or full stroker.

3. Swap logistics and necessary control packs/harnesses.

esh update on the Ford 7.3L Godzilla Engine reliability, fixes, and new high-performance crate options :

 Lifter & Lifter-Related Issues Ford 7.3L Godzilla Engine

• In early production models, lifter failures—often followed by cam damage—were reported. Many were tied to low oil pressure at idle and defective oil pump tuning

• Fortunately, Ford released a PCM software update to adjust the variable‑oil pump and improve lifter operation

Reddit Owner Reports:

• Early issues were most common in 2020–2022 (especially vans/E-series and high-idle usage); from 2023 onward, significantly fewer reports and fixes applied

 Other Common Problems & Owner Advice Ford 7.3L Godzilla Engine

• Clicking/tapping noises, particularly on acceleration, often signal collapsed lifters; uncertainty remains whether it’s dealer oversight or lifter wear

• Some engines at ~90–140k miles encountered cylinder scoring and low compression after lifter/cam damage Other less frequent issues: wiring-harness failures, transmission (10‑speed TorqShift) shift roughness, and occasional oil consumption

 Recommended Pre-Purchase Checklist & Updates

• Prioritize 2023 or newer model years to minimize early-production risks.

• Confirm with dealer that PCM software updates for oil-pump/lifter issues have been applied.

• Get service records: oil change frequency, PCM updates, inspections for metal debris. Higher-mileage units with good maintenance (particularly synthetic oil) are more stable ally checking oil samples and filter debris—for hidden wear .

 High-Performance Crate Engines & 2025 Lineup

• Ford is releasing the Megazilla 2.0 supercharged Ford 7.3L Godzilla Engine—that’s built for competition use—promised in late 2025 with up to 1,000 hp

• Earlier in 2025, Ford Performance launched a supercharged Ford 7.3L Godzilla Engine “Megazilla” for street & race, debuting both street-legal and competition versions toward the end of the year .
