4.6L/270HP Jeep Long Block

We build each 4.6 Jeep engine to be an easy direct fit in place of all model year 4.0L efi engines 1991-2006 as well as the earlier CJ Jeeps that have 4.2L engines with a carb.  Your stock transmission and front and rear differentials will work fine with the 4.6L Jeep stroker engine as this is what most customers use when making the swap and the Jeep Stroker welcomes larger 33" plus tires. Making over 300 ft lbs of torque you will not have a problem climbing hills or towing a trailer and best of all the Jeep engine gets great fuel economy while passing emissions in all 50 states. With a smooth idle this engine loves daily driving, rock crawling, highway travel and trail runs!!
