AUSTIN Hot Rods Roll In The Roth and Ronnow 1927 T-Roadster. The Khougaz Roadster. The King and Hansen Belly Tank. Getting a close-up look at these and a hundred more or so pre-1948 hot rods and customs is the point of the Hot Rod Revolution. Started five years ago in Santa Rosa, Calif., as a party for finicky gear-heads, it has moved to Austin this year because the city is an equally friendly environment for engine-revving. Needless to say, these are more than just old cars they are the pinups that have graced the covers of magazines and set speed records on the Bonneville Salt Flats in Utah. Such a world-class lineup presupposes overbearing owners who dont want you breathing on their wax job, but not so at the Revolution: No ropes will cordon off these rides from the public. The setting, the decommissioned Seaholm Power Plant, doubles the pleasure with its panoramic riverside views. Seaholm Power Plant, Nov. 20, 10 a.m. hotrodrevolution.com
