For this Tech 101 segment we head back to EFI University (Youtube: @EFIUniversity1) where Ben Strader shows us a genius hack you can do at home or in your shop to quickly and easily test gross valvetrain stiffness.
Using our Expo engine, a flow bench checking spring, and a real spring, Ben shows us how easy it is to measure how much bending and flexing is going on in your valvetrain so you can build a stiffer system and squeeze more RPM from your engine.
