“We have so many engines we’re doing here we have a library of camshaft profiles … but it takes common sense. You take what the engine will be used for, what rpm, how much compression, what kind of car it’s going in, what it weighs, what gear ratio, until you know everything about that engine. Then you figure out exactly what you need for a camshaft. I do the same thing with pistons, piston rings. I’ve been doing this for a lot of years, taking advantage of all the experience I have, always learning the hard way, making mistakes. They’re plugging me into the areas they need my expertise in. All 31 people who are working here, I’ve hired. The engineer has been here 31 years.
