Our solid flat tappet cams offer superior performance and the very best value. These grinds are tried and tested!

Note: This cam is not drilled for an accessory drive. 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 flat tappet cams DO NOT have this modification. (Our roller cams already have this modification incorporated when manufactured.)

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.
