As an related aside:
I used to work at Rochester Products; my manager in Product Development was the guy who developed and patented GM's fuel injection system. I don't recall his name right now, but it wasn't John Dolsa. I also remember pulling up the patent and seeing my manager's name on it.
He was a inventive-type genius with a good memory. That was 20 years ago, I'm not sure he's still around.
They also had an original mechanical fuel injection system in the lobby, next to all the new-fangled electrical ones.
