History

The Barracuda was acquired in 1987 as a tired street car. The original plan was to build the Barracuda for street/strip use with the drive train from a “340” Duster or Dart. However things got out of hand and the Barracuda became a race car. The completed Barracuda included a full roll cage, a modified 340 Chrysler small block, 727 automatic with a Turbo Action valve body and 8” race convertor, an 8 ¾ rear end with 4.88 gears and Strange axles. The race car was also equipped with Mopar Super Stock springs, Centreline wheels and 9 x 28 inch Goodyear Slicks

The Barracuda made its first appearance at Saskatchewan International Raceway in May 1988. It ran low 12 second ET’s at 112 MPH. Modifications over the next four years improved the Barracuda to 11.50 ET’s at 115 MPH.

In 1991 the drive train and most of the race parts were transferred to a second tired 1965 Barracuda that became Diane’s first race car. The original Barracuda was reconstructed as a NHRA Superstreet race car to run the Pro Tree 10.90 Index Superstreet Sportsman class at NHRA Divisional and National Events. The Barracuda ran in NHRA Superstreet until 2004 when it was parked to await a much needed rebuild.

Beginning in fall of 2009 the rebuild began and was completed in April 2011. The Barracuda returned to the track in May 2011.
