This a professionally converted 5.3L engine conversion. I have built several custom cars over the years and I always do it the “right” way. I took a relatively stock LJ with a higher mileage 4.0L auto and completely rebuilt mechanically in every aspect. Would make a great start for a true rock climber or keep it as is for a daily driver. The Gen 4 LMG engine is a great stock platform with so many after market performance mods available.
