Gotta love these awesome LT-4’s…they respond very well to just a few mods! We took this one in at 574 rwhp & 550 ft/lbs (already killer right out of the box). With a cold air intake, Kooks Headers and Exhaust and a Redline Motorsports lower overdrive kit, we picked up 87 rwhp & 93 ft lbs of torque, ending up at 634 rwhp & 643 ft/lbs of tq!
