The "Rocket Box" borrowed technology from
engine exhaust nozzle design to improve the flow of air/fuel between the
Quadrajet carburetor and the Edelbrock Torker. Hence the nickname "Rocket Box".
There was also some positive effect due to the increased total plenum volume.
The "Rocket Box" idea came from Craig Hendrickson's educational background
and professional activities before H-O Racing. Craig has a B.S. in Astronautical
Engineering from the USAF Academy and an M.S. in Astronautics from Purdue Univ.
Craig worked for NASA on the Apollo missions as an Astronautical Engineer and then for the
USAF on the Defense Support Program as the Orbital Operations Officer. It seemed logical
to Craig to try to adapt some rocket science to automotive high performance.
