Next up was was a 1966 Stage II Yenko Stinger based out of Springfield, Missouri. Yenko Sportscars recommended the 190 horsepower Stage II Stinger "for high-speed touring, rallying," or as a "dual-purpose race machine," noting that the Stage II engine would "afford the buyer high performance without sacrificing any the the desired reliability and smoothness of a street machine."

Specifying that the engine was tested at 190 dynamometer clutch brake horsepower, Yenko claimed the Stage II would "easily out-accelerate all of the street variety V-8s and most of the so-called high performance cars" of the day. It was equipped with a polished crankshaft, select fit main bearings, pistons notched for additional valve clearance, select fit piston skirt clearance, a high performance Stinger camshaft with heavy duty valve springs and retainers, 10 to 1 compression ratio cylinder heads, a lightweight flywheel, modified engine cooling fan, deep sump oil pan pickup and horizontal oil control baffle. All this was on top of the special Stage I equipment such as a seven-quart finned aluminum oil pan, tuned exhaust headers, constant tension belt retainer, and dual master cylinder brake system.

At right, we see a close-up of the 14" Minilite wheels seen dressing out the Stage II in the picture below.

As indicated in the Yenko section of this site, 220 horsepower Stage III or 240 horsepower Stage IV Stingers were also available. The Stage III machine was recommended for that day's Sports Car Club of America (SCCA) D Production class, and the Stage IV was recommended for "high-speed touring or rallying," and was "illegal for SCCA racing."

The higher horsepower ratings were achieved through the use of shaved, ported, polished and relieved 10.5 to 1 compression cylinder heads, cylinder walls honed to racing clearances, full float piston fit, adjusted piston deck height and a reworked high performance distributor. In the case of the Stage IV car, displacement was increased from 164 to 176 cubic inches.

Above, Stinger YS#095 is a serious looking competition machine. I wondered why it was wearing Texas paint and Missouri plates. According to Charlie Doerge, Registrar of the Yenko Stinger Registry, the car has changed hands a few times. Dave Davis, General Manager of Young Chevrolet in Dallas, sold it to Mike Philips, who sold it to Chris Langley, who sold it to Curtis Wood, who sold it to its current owner, Jeff Moore. Think it might be for sale?
