Duel? That movie cracks me up. Chester freaks out when he gets up to 60 MPH.
No, Weave freaks out because he didn't have any more under the hood! Up there in the mountains, that do tend to happen. I was in a '66 Pontiac Tempest once with a 326 4V under the hood burning hi-test, loaded down with six people and luggage, and I saw how it labored trying to get across the Raton Pass in New Mexico, up in the Sangre de Cristos, on the Interstate. At the top of the pass, the driver was all the way in it and he couldn't get it above 30 mph. No joke, bloke.
