4.0l stroker kits? - Jeep Enthusiast Forums

pros and cons stroker inline 6 vs supercharged 4.0
Sep 27, 2013 · wsar10. 2348 posts · Joined 2008. #10 · Sep 27, 2013. Actually I think its more efficient to stroke a 4.0 than upgrade to V8. purely based on cost and power/weight ratio. There was a powerblock episode where they stroke an XJ and IIRC the torque in the end was the same as a V8 with half the motor weight.

Stroker Fuel Mileage - Jeep Enthusiast Forums
Jun 18, 2012 · Regarding stroker kit, yeah not much gain for the money. I have "heard" of guys swapping in a late model Chevy 5.3 and accompanied transmission and getting around 22mpg if driven conservatively.

A weeks worth of getting up at 5:30am to work for 1.5 hrs before work on removing everything from the engine bay and I was ready to pull the engine!
