The STM 650 Cams are designed for the Evo 4-8 making at least 650+ wheel horsepower on a Mustang Dyno or looking for 155+ mph trap speeds in the quarter mile. STM is now teamed with Kelford Cams to produce the record setting specs of this particular grind.

If you’re building a high HP 4G63 engine and are not sure which cams to run… let us set you on the right path. On the STM Evo RS build, and on all our high HP builds, we use the STM 650 Cams. The RS set the bar for the Evo 8/9 1/4 mile goals with an 8.0 @ 182 and held that record for fastest CT9A for 3 years.
We can drill you with charts and graphs all day, but we strive for the true results that are not just at the end of the quarter, but felt in street driving as well.
