In Episode 18 COMP CamsBilly Godbold does an educational session on valvetrains and how low shock technology has become the standard for power and durability across the spectrum of race engines. He goes through how we were all taught to compare profiles and how we now need to “re-learn” based on the new technology.

Along the way he talks about everything from the pros and cons of roller and flat tappet camshafts to the importance of resonance in creating more power.

After the educational session, Joe Castello and Lake Speed Jr are joined by Billy for live Q&A from the audience, as well as a few great stories from Billy, including some NHRA insider tricks, and how Jon Kaase once found a way to lose 300 horsepower and brag about it.
