eat your heart out, tony soprano.
The Lingenfelter 9.9L (605 cubic inch) V8 was a massive, custom-built engine installed by Lingenfelter Performance Engineering into Chevrolet and GMC Suburbans, most notably a 1994 GMC Suburban and some 1999 Chevrolet Suburbans requested by the Saudi Arabian government for law enforcement. This ~10-liter, marine-based engine produced approximately 550 horsepower and over 700 lb-ft of torque, giving the large SUVs blistering acceleration for their time, with 0-60 mph times in the low to mid-4-second range.
Key Features:
Engine Size: A ~10-liter (605 cubic inch) V8, often described as a modified marine-duty block.
Power: Approximately 550 horsepower and over 700 lb-ft of torque.
Application: Modified Suburbans, originally intended for the Saudi government as high-speed pursuit vehicles.
Performance: Achieved 0-60 mph times in the low to mid-4-second range, a feat considered exceptional for a heavy SUV at the time.
Rarity: Only a handful of these high-performance Suburbans were believed to be built.
Origin:
The Lingenfelter 9.9L project began when General Motors was approached by the Saudi Arabian government for a more powerful Suburban. GM then passed the project to Lingenfelter Performance Engineering, which developed the massive V8 engine to meet the demand for a high-speed, heavy-duty law enforcement vehicle.
