From nearby Elk Grove, CA, Roy Castagnetto brought his '56 Chevy Pro-Street pickup. For obvious reasons, he calls the truck "Plumsik." The 871 blower and 509ci big-block mill makes a ground-shaking 932 horsepower. Thankfully, there's a Ford 9-inch for the Pro-Street meats to put all that power on the pavement. Darin Houston, the truck's painter, went plum crazy with purple.
