Commercial Break: Keystone Wheels, 1977 (US)

United States GP West, Circuit Long Beach, April 3, 1977

An already tragic Formula One season received exactly what it needed to chase away the despair when the brilliant Mario Andretti became the first American to win a Grand Prix on his home soil. After the deaths of Tom Pryce in the South African race and Carlos Pace in a plane crash, the United States Grand Prix West was a glorious triumph for Andretti. It was the start of his two-year march to the World Championship, and the first win for the car that would usher in the ground-effects era, Colin Chapman's Lotus 78.
The picture shows Patrick Depailler in the Tyrrell P34B; he would go on to finish 4th in the race

Pro Street 1977 Chevrolet Monza - Latter Day Hero

A car that looks like its rolled straight out of a 90's magazine, today. Pro-Street was huge at one point; it seemed everyone and his dog had a back-ended car with 10x15 rolling stock at the blunt end. But like most car crazes, there were great exponents of the art and mere pretenders; cars that looked the part but didn't deliver on the drag strip, which after all was the whole point of Pro Street. The movement died away, but some people loved the style so much they harboured dreams of building a modern-day version.
This particular car is a Chevrolet Monza, based on the Vega floorpan and billed as a rival for the Ford Mustang II. While they are largely forgotten about by everyone except the hardened petrolhead, they make an absolutely fantastic base for a Pro Street hero. And the best thing is, with a modern 450bhp, 364ci LS2 Corvette V8 inked to a Tremec six-speed gearbox, this monster Monza ain't all show. Heres to a Pro Street revival.
