Most people familiar with Brock Racing Enterprises immediately think of John Morton and the Datsun 510. With good reason. The boxy red, white and blue No. 46 BRE car won the SCCA 2.5-liter Trans-Am championship in 1971 and 1972. And the affordable 510 adapted so well to racing that scads of them, many painted like original BRE cars, popped up at racetracks around the country. Even today you'll see the occasional 510 road racing, often in BRE-inspired paint.
