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.

Howards Cams direct lube hydraulic flat tappet lifters use a precision minor flat ground on the side of lifter body to supply oil to the cam lobe/lifter interface. This allows for a constant oil supply to the cam lobe, resulting in higher valve spring pressures, more aggressive profiles, and reduced lobe wear.

Howards Cams Big Daddy Rattler camshafts are street performance cams designed to give a nice aggressive-sounding idle without sacrificing throttle response and horsepower gains. Big Daddy camshafts are top dog in the Rattler lineup, and as such they offer a rough idle, and are best used in Pro Street or street/strip applications. Compression needs to be at least 9.5:1, the torque converter needs to stall 2,800 rpm or higher, and a performance intake manifold, steeper gears, and free-flowing exhaust are required to take advantage of the camshaft's capabilities.
