This is a great comment, "dubbed the fastest car in the county."  Jim said the limiting factor was the Ford clutch and pressure plate.  They considered a multi disc clutch but heavier pressure plates became available.  Evidently the Offy was a torque beast. 

This is a shot from an early race-before the roof scoops.  By the way Ted and Joy could take one small child in the back. 

This is Joy Cannon torqueing the lug nuts.  She was a trooper for putting up with the Cannon and Seely boys.  Jim was an uncle to the Cannon kids.  The two families are still close. 

This is a picture from Road and Track Magazine.  Notice the scoops in the roof.
