Our 1993 Jeep Cherokee Sport needed its tired engine rebuilt, so we figured why not give it a decent upgrade while we’re at it? Of course, we wouldn’t miss the opportunity to shoot time-lapse video of every step along the way and hit you with another amazing addition to our Redline Rebuild series! With help from our friends at RockAuto.com, we source a crankshaft and pistons from a different Jeep engine (4.2L) and stroke this XJ’s legendary 4.0L straight-6 AMC engine to a slightly more powerful and torquey 4.6L.

Alguien me ayuda con la marca o el fabricante de ese kit de motor
great entertainment… I don't have TV, so I watch a lot of this type of content. I never plan on doing this type of work since I play guitar and don't want to damage my fingers. None-the-less I find this program to be my favorite. Keep them coming
How much to do this to mine?
i did a 4.6 stroker in our XJ years ago. it made me love that rig. so much fun! we had 4.56 on 33" tires with an automatic. perfect!
Nice video, Good engine
