This 73 Grand Prix has been in the family for 31 years and was purchased by my father. After working on this car for 8 years I have finally achieved my dream of making it the street ripper it is. For a 4000 pound car it really moves I achieved a 14.6 at 92mph at Raceway Park. My 60 foot time was one of the fastest there at 2.1. 3.70 Gears were the key to this.
