This is a factory original GS 350 car that I have upgraded to a 455 car. The current 455 engine and matching turbo 400 transmission are out of a 1970 Buick LaSabre, the engine suffix code is SF.

The transmission was also rebuilt in August 2003 by Detroit Transmission, Denver, CO. The rebuild included a new 1800 RPM stall convertor and a mild shift kit.
The body and paint work was done in August 2002, and was a body-on restoration. The car is painted in Fire Red base coat/clear coat.
