Engine builders and automotive machinists have certain "go to" specialists they rely on for items such as Powerhouse Products Pro-Series lifter bore grooving tools. These innovative devices--developed by a NASCAR expert--precisely groove the lifter bore to ensure that more pressure-fed oil is injected directly into the contact area between the lifter and camshaft. Result? Reduced wear on those parts, with less risk of premature failure. This machining operation to the block is quick and easy…so get your groove on, guys.
