Underhood, things are squared away completely. The potent Coast High Performance 347 with all of the aluminum goodies added on makes a package long on torque and short on weight. The free-breathing air-cleaner filters at both sides and top make for little inlet resistance. The chrome tower brace, Monte Carlo bar, and Ford Racing rocker covers round out this good-looking picture. Remember, the bigger the displacement, the more radiator you'll need, and Casey has a heavy-duty aluminum unit already installed.
