Also From the Richmond Times-Dispatch: General Motors, meanwhile, has been trying for two years to push through its new SB2 engine package, with low-angle valves and straight manifold runners similar to the Ford package. There was widespread belief that NASCAR would allow the new engine, perhaps later this season. But that project also is not on the fast track, GM engine men say. John Wilson, engine chief for Bobby Labonte, said the heads and manifold of the SB2 had gone through several modifications and that the latest formula would be submitted to NASCAR in the next week or so. He said, however, that he had no assurance the parts would be approved. “At one time I thought it was an open-and-shut deal,” Wilson said. “Now I’m not so sure.” Wilson said the new package needs a lot of work. It shows good horsepower on the dynamometer but is not as good when put in a car on the track. “It just doesn’t accelerate,” he said.(5-18-97)
