This JK Wrangler came to us with 6,000 miles on the clock. The customer wanted more power and better reliability then the stock 3.8. He chose a LS3 corvette engine with a 6L80 automatic. The swap is super clean and looks like factory! All the factory gauges, cruise, ac, and traction control still work, but there is a whole lot more power. Hemi conversion engines are a norm for these vehicles, putting a GM LS3 in a new JK now that's cool!!
