Chris Kuskowski
1972 Plymouth Duster

Peek under the hood of Chris Kuskowski's gleaming 1972 Duster and you might be surprised at what you see--a small-block among a sea of F.A.S.T. big-block competitors. The scrappy Duster started out as a very solid six-cylinder machine that had been cloned into a 340 car. The current engine is based on a 1968 340 and now boasts a 4.25 x 4.08 bore and stroke, giving it a total displacement of 444 cubic inches. Inside is a Callies Magnum crankshaft, Callies Compstar 6-inch connecting rods, Diamond pistons and a Comp Cams solid-roller camshaft. Chris topped off the short-block with a pair of 915 J heads rebuilt and reworked by Porter Racing Heads, giving the package a 13.6:1 compression ratio. The transmission is a rollerized 904 with a column shift (the column shift setup is lighter than a floor shift and console) and a reverse manual valve body, while the rear is an 8¾-inch Chrysler with 3.73 gears and a spool. As with many of the F.A.S.T. cars, an aluminum driveshaft helps keep weight down and RPM up.

To help the car transfer, the Duster is outfitted with Slant 6 torsion bars and Competition Engineering drag shocks. A set of Espo reproduction 340 rear leaf springs with polyurethane bushings keep the G70-14 Polyglas tires (on Wheel Vintiques SBP 14 x 6-inch Rallyes) planted to the track surface.

The car was originally dark brown metallic, but Chris opted for a red PPG basecoat when he painted the car. The finish is outstanding, especially considering that Chris, an engineer by trade, painted the car in his home garage--where he also built the engine. The Duster lays claim to being the fastest small-block powered machine in F.A.S.T. with an ET of 11.43 at 120 MPH.

Best ET/trap speed: 11.43 @ 120 mph
