Question 1

What's the horsepower and torque output of the Golen 4.6L Jeep stroker engine?

Accepted Answer

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.

Question 2

Will this 4.6L engine fit my Jeep Wrangler, Cherokee, or Grand Cherokee from 1991-1999?

Accepted Answer

Yes, this stroker engine is designed as a direct replacement for all 1991-1999 Jeep models originally equipped with the 4.0L inline-six. This includes Wrangler YJ/TJ, Cherokee XJ, and Grand Cherokee ZJ models. The engine uses factory mounting points and includes year-specific Bosch fuel injectors for proper compatibility with your existing fuel system.

Question 3

What makes this stroker engine better than a rebuilt stock 4.0L?

Accepted Answer

The 4.6L stroker increases displacement by 15% through precision boring and a performance crankshaft, generating substantially more torque. Unlike basic rebuilds, this engine features forged steel rods, balanced rotating assembly, performance camshaft, professional head work, and dyno break-in testing. These upgrades provide racing-quality reliability and performance far exceeding standard rebuilds.

Question 4

Does the engine come with a warranty and technical support?

Accepted Answer

Absolutely. Every Golen Engine includes a comprehensive one-year warranty with no mileage limitations. You'll receive full phone tech support at 603-886-3800 ext 2, complete installation guides, and detailed spec sheets. Mandatory pre-startup consultation ensures proper procedures, protecting your investment and maximizing engine longevity.

Question 5

How long does shipping take, and is the engine ready to install?

Accepted Answer

The 4.6L stroker arrives as a complete, turnkey engine ready for installation. It includes all gaskets, injectors, oil pan, timing cover, and valve covers. The engine has been dyno break-in tested with Joe Gibbs Racing oil, eliminating critical initial wear. Contact Golen Engine for current lead times and shipping options to your location.
