This really nice 2008 Jeep JK Wrangler Unlimited has grown a bunch since it left the factory. The heart has almost doubled in size from either a 3.6L or a 3.8L V6 to a 6.1L Hemi V8. The 6.1L Hemi was made from 2005-2010 and produced 425 horsepower and 420 ft-lb of torque. That’s roughly twice the power and torque from the factory engine. The swap was performed by AEV Conversions in Commerce Township, Michigan and they also offer a JK/Hemi swap kit for those DIYers.
