He probably knew more about Oldsmobile engines than anyone else on the planet, especially when it came to making horsepower. Mondello became known as "Dr. Oldsmobile" based on the fictional character who wore a white jacket in the performance Oldsmobile ads.
GM officials took note of his cylinder head savvy and he was tapped to design many of GM's cylinder heads. His cylinder head designs were used by the Who's Who of racing greatest such as Carol Shelby, Don "Big Daddy" Garlits, Don "The Snake" Prudhomme, Tom "The Mongoose" McEwen" and many others.
Mondello was also a GMC motorhome enthusiast later in life. He and has wife Mary were Eastern State Club and Dixielander members in addition to attending a couple of GMCMI conventions. He had a wealth of knowledge about Oldsmobile engines and he enjoyed sharing it with club members at rallies.
I recently came across an article written by Mondello titled "Rebuilding Your First Engine." This is a six part article with step-by-step instruction on how to rebuild Oldsmobile engines.
