My younger brother had a tendency to go thru cars at a young age. He was in high school in the early 70s. My dad managed to come up with an early Pontiac Firebird with the overhead cam 6 in it for him to drive. He wreaked it shortly after. Next up dad found him a 68 GTO Judge. He blew the V8 up in short order. Dad found someone who put the OHC 6 in the GTO. That lasted a little while until he put it up against a guard rail. And the story goes on.
