There is a limited number of places that make flat tappet cam cores. Most of the cam companies get their flat tappet cam core from the same place. Now the question is what does your cam company with the flat tappet cam core?

Along the same lines is that many companies also buy for a better term white box cams which are already ground and ready to sell.

Also the radius on the bottom of the lifter needs to be matched to the tappet ground on the lobe.
