Flat Tappet Lifters & Roller Lifters | Tech Lab Tuesday

For this week's Tech Lab Tuesday we're dipping into the David Vizard vault again to get his take on lifters. 

David Vizard's PowerTec 10 EP 15 When Flat Tappet Lifters Reign Over Roller Lifters talks about times when Hydraulic lifters are the better choice. Sure roller lifters sound better because others you know chose the roller tappet path but what makes you so sure its right for your application. So yes there are times when a flat tappet lifter cam can, for the same or less money, out perform a roller lift cam.

Thanks again to David Vizard for allowing Goodson to share his wisdom and experience with our readers.
