1966 Buick Wildcat

The 1966 Buick Wildcat remained much of the same with an addition of the Wildcat Gran Sport option that was only offered in '66, and included a chrome-plated air cleaner, cast aluminum rocker arm covers, dual exhaust, heavy-duty suspension, Posi-Traction rear end, and GS identification plates for the front and rear. This engine and performance option was known as the Y48, A8 or the Wildcat 465 and was rated for 380 hp. A very rare option with less than 25 believed to be produced. The non Y48 / single quad carb engine was rated for 360 hp. The "465" sticker on the air cleaner denoted the torque rating. The Y48 option included ONLY the dual quad carb option. It was delivered in the trunk and dealer installed. The GS package also included variable rate suspension springs, heavy sway bars, quick ratio steering box, 3.42 axyl ratio and switch pitch turbohydramatic 400 transmission.
