Are you having a difficult time finding the cam profiles that you want? Do you have a specific lift rule or duration rule at the race track that you run on? Maybe you have a particular cam profile in mind but no one offers it. Trying to get a camshaft grinder to design a cam profile just for you is almost impossible. It is just not cost effective for them to put in the time to design a special profile that may not be a big seller. Most would rather sell the profiles they already have. If they were to design your cam profile, the cost would probably scare you away.
Let me know what cam specifications you are looking for and I will gladly give you the time. Sometimes certain cam specs will not produce a good profile. I will be able to tell you if your cam specs will work or not. We can also discuss altering the specs if that is necessary.
If you decide to have me design your cam profiles, you can then send the design data to the camshaft grinder you choose, and have a camshaft made with the profiles that you wanted.
