For episode 56 Lake Speed Jr takes us back to “professor” John Callies’ shop for a lesson on lifters and bushings.

John breaks down how lifters play into the quest for more horsepower and why they used to fail so often. He also shows us the difference between needle and bushing bearings, why bushings give better load distribution and bearing capacity, and secret behind keyed lifters.

Finally, John provides us with look at the technology that goes into creating a lifter that makes an “oil wedge” that provides better oil distribution for the lifter whether it’s for racing and/or street applications.

    The presentation could have been more informative if Lake Speed allowed John Callies to speak without interruption. We were listening to hear what John Callies had to say not Lake Speed. This is disappointing session that could have been much better with only one presenter.

    Would have been a great presentation if the young guy would have kept quiet!
