I have been building race(car) motors for around 20 years and for as long as I can remember, when you bought a cam from one of the aftermarket companies you received the spec sheet with it. You could also go to your local speed shop and look up the company and cam specs that you wanted. As a matter of fact, the aftermarket cam makers for Harley engines will give you the specs so you can make an informed decision on what type of cam you'll need for the power band you will be riding in. So why is TPUSA keeping theirs a secret?......Angelis
