Mike Rauscher of L&M Engines (left) is the braintrust behind the brutally fast Coyotes that have taken Evolution-built '11s and '12s into the 8-second zone on the dragstrip. Prior to installing the Stage 3 cams used in this effort, Mike "spun" each cam using an elaborate cam-profiling machine and software to learn details that go far beyond the stats listed on the cards included with each cam. "The Comp cams are designed with emphasis on exhaust (longer duration promotes later valve closing), which is exactly what we want with the new 5.0 engines and the upgrades you're featuring. I think the cams will really work well on the naturally aspirated 5.0, but engines with power adders (like superchargers) will really benefit," Mike says.
