🔥 Twisted Street™ Big Block E4OD Performance Transmission – 400 HP Rated

BIG BLOCK GAS APPLICATIONS ONLY

Ford E4OD • 1989–1997 • 7.5L / 460 EFI

Heavy-Duty Daily Driver • Towing • Work Truck • RV & Motorhome Use

The Twisted Street™ Big Block E4OD Performance Transmission is engineered specifically for the high torque output, heavy vehicle weight, and sustained load demands of Ford 7.5L / 460 big-block applications.

Big-block applications require stronger frictions, improved clutch capacity, upgraded bands, better hydraulic stability, and a heavy-duty converter simply to survive factory torque levels — and this build delivers exactly that.

Designed for towing, hauling, RV and motorhome duty, plow trucks, fleet vehicles, and heavy daily-driven Ford big-block applications.

Built and calibrated the Twisted Torque™ way for long-term durability and dependable operation under load.

🔥 IDEAL APPLICATIONS

• Stock or mildly modified 7.5L / 460 EFI engines
• Work trucks & fleet vehicles
• Light to medium towing
• RV & motorhome chassis
• Snow plows & utility rigs
• Heavy-duty daily drivers

Rated to handle up to 400 HP when properly matched to vehicle use and cooling system requirements.

🌡️ HEAT MANAGEMENT REQUIREMENTS

For ALL big-block E4OD applications:

🧊 External auxiliary transmission cooler REQUIRED

🧊 Cooler and transmission lines must be flushed or replaced

🧊 Deep transmission pan strongly recommended

🧊 Additional cooling strongly recommended for RV, towing, and plow applications

🧊 Transmission temperature gauge strongly recommended

Heat is the #1 killer of big-block E4OD transmissions under towing and sustained heavy-load conditions.
