A nice case study on reverse engineering parts. (Spoiler alert! here's the ending:)
As the first manifold came off the CNC machine, it was taken to the engine shop for polishing and testing on the dynamometer. The manifold generated the same peak power as the original, and the power curves were nearly identical. It was installed in the engine of the car driven by Jeff Burton, and sent on its way to the next race – the Pocono 500.
