I was just reading aarcuda's comments in another thread, and the "deuce and a half" came to mind. Also, the Jeep.
I Googled up the old deuce and a half. WOW, a whopping 104 horsepower! And IIRC, the early forties Jeeps were 60 hp.
You can do a lot with gearing and engineering, but, sometimes, there just ain't no substitute for power.
Ah, the good old days. You'd always get there. Eventually.
