The Cota Brothers have recently completed installation of a LS3 in a 1963 Nova Wagon. The stock clip and steering box was used as well as equal length headers and power brakes. No sheet metal was cut to install motor or 4l65E transmission. All together the Nova weighs 2985 pounds. Without a tune the motor is still pushing out 486 horsepower and 465 ft. lbs. torque.
