Power means little unless it can be harnessed and Corey Thompson is putting all the key components together to make it work on his 1970 Firebird. With over 1 horsepower per cubic inch of displacement, his 400 stroker engine is powering his Firebird down the 1/4 mile in just under 10.50 seconds. Realizing that stock components are not capable of handling the high torque his engine makes, Corey has taken great efforts to improve the frame, driveline and suspension of the car. Corey's race engine was recently inducted into PSP's 1 to 1 Club (2009). The engine and components are featured below.
