i bought a special grind cam from Total Performance, looking back i wished i would have called around to some of the cam companies, but this cam should work okay should have it going in a few weeks like broncoaz said call the companies and tell them what you have and if their tech support is does not ask a lot of questions, like gearing, transmissions, etc then move on to the next company i seriously doubt there is a large difference in the quality of the major manufactures if you do not understand camshafts read up on them on the internet or get a book on windsor small block performance that bump stick makes all the difference in the world understand it before you buy it and you will be happy with your choice just cause it works in one rig does not make it right for the next
