In this episode Billy 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 Billy’s seminar, he joins Joe Castello and Lake Speed Jr in studio for live Q&A from the audience. Billy also tells a few great stories, including some NHRA insider tricks, and how Jon Kaase once found a way to brag about losing 300 horsepower.
