Frank McGurk was an actual person and one of several Chevrolet six cylinder guru's of the time along with California Bill Fisher and Eddie Edmunds.
Tom, I have some photo copy information on the McGurk cams and I have a McGurk cam. According to the information I have, the McGurk cam I have is a "full race" cam. Someday I intend to build the 62 - 261 I have on an engine stand and use that cam. Let me know if you need the information and I'll get it to you.
