FAQs for 1991-1999 6 Cylinder Engines Q1: What’s the horsepower and torque output of the Golen 4.6L Jeep stroker engine? A: The 4.6L stroker significantly increases displacement from the factory 4.0L, delivering enhanced low-end torque ideal for off-roading and towing. While exact figures vary based on optional upgrades, customers typically experience 20-30% torque gains over stock. The forged internals, performance camshaft, and optimized valve job ensure reliable power delivery throughout the RPM range.
