Dimensional Inspection Laboratories (DIL) uses computer-assisted coordinate measuring machines for dimensional inspection on everything from medical equipment and space shuttle components to computer parts and chocolate bar molds. On this day it was Edelbrock manifolds. Blundell doesn’t need dimensions on the entire manifold, just those that relate to building fuel rails—the relation of the manifold to the fuel fittings, locations of fuel inlets, bolt patterns, carb centers, and surface heights, among other coordinates. In the past, Blundell would have inspected the parts manually, which was time-consuming and less precise. Working with Sean Wertens at DIL, he can now build a three-dimensional model in the computer that he will use to build production tooling, confident that everything is squared, aligned, and dead center and that his customers are getting accurate fuel rail systems that assemble easily and operate smoothly.
