Clevite V-Series Rod Bearings
If you liked the results that you used to get with Vandervell bearings--especially their higher conformability--then you should love Clevite V-Series rod bearings, which basically duplicate the Vandervell items. Built on un-plated, hardened-steel backings for better dimensional accuracy and bore contact, they have low-to-medium eccentricity. The biggest difference between V-Series and other Clevite 77 bearings is their lead-indium surface alloy, which gives them that extra conformability. V-Series bearings are available in narrower versions to provide greater crank-fillet clearance, as well as in extra-clearance variations that provide an additional 0.001 or 0.002 in. of clearance.

Howards Cams Direct Lube Extreme-Duty Mechanical Lifters
Today's cams have more aggressive lobes. That's why increasing the oil supply to these lobes is critical. Howards Cams uses a precision "E.D.M." laser to burn a .021 in. hole in the center of the face of their direct lube extreme-duty mechanical lifters. This allows for a constant oil supply to the cam lobe, resulting in higher valve spring pressures, more aggressive profiles, and reduced lobe wear.
