470 dyno test article

Here is the latest dyno test article with my pump gas 470. In this article I tested a belt driven oil pump as well as a vacuum pump. Peak power was 775 hp on unleaded pump gas. The Wilson porting helped out a bunch as did the vacuum pump. With this kind of power you should be able to drive to the track and run 9's in an A body car.
