Frank passed this morning due to complications from a blood clot. He had suffered from diabetes for a very long time, and that likely contributed to his passing.
Back in my early racing days in the '60's and '70's he was the absolute expert on teching FV and FF engines. There was no one who knew more about those subjects and was a more thorough and respected inspector back then. After the 1972 ARRC (now Runoffs) we got to spend ~6 hours in the no-wall Road Atlanta tech shed with 35 degree wind blowing through as he measured and weighed every part of my FV engine.
We got to know him (and his wife Shirley who passed a few years ago) better later on and they were very interesting company as we rode with them on a trolley tour of Savannah after the 2013 FV 50th at Roebling Road.
RIP Frank. We'll miss you.
