Great performance at low, low prices! Cams not drilled for accessory drive.
Tech Tip:Many sprint cars use a fuel pump, power steering, or dry sump oil pump mounted to the rear of the engine which is driven off of the back of the camshaft. This requires that the cam be drilled and tapped for the drive spud. Our oval track roller cams already have this modification incorporated when manufactured. Our flat tappet cams (such as the 915-12005) do not have this modification.
If you are running a sprint or modified that uses a rear cam accessory drive and your local rules dictate that you run a flat tappet cam, you will have to take the cam to a competent machinist and have it drilled and tapped for the drive spud.
