You guys need to buy you an inexpensive degree wheel....and a dial indicater..they can be bought inexpensivley too. Then you can check those cams you have there...and later when you get better stuff to race with...you can learn about your race cam too. The two you have there...Id be surprised if you see much differance in either one....lift,duration, or base circle. If you plan on being in racing...these are indespensable....and you need a good timing light to set your timing with too. Its not that big of an investment.
