their whole /engineered series looks to be pretty good, skimmed over a few videos. Definitely a great watch if you're into technical stuff more than some cars revving and doing burnouts
I saw that a while ago. Its an entertaining series.
Interesting tidbit with the size of the camshaft cores. I never thought about it that way. But the larger diameter cam core allows for a gentler valve train while retaining the crazy ramp rates modern cams have.
