I had reams of dyno documentation on a Ford 300 6 cylinder until some pea-brained school administrator decided to do some housecleaning in my shop during summer break one year. He emptied a bunch of filing cabinets with dozens of dyno run sheets on about 50 different engines, street machines and round track race engines! He also trashed Motor service manuals covering vehicles back into the 1940's- - - -"They were dirty and looked bad in the book shelf". He couldn't understand why I never had time to get the students to do a tune-up or a brake job on his car after that little incident!
