    best way to tell is if you got a stock cam and you put it next to it. Not all cams are equal as some will open the valve sooner and more. Some wont. If you had a stock cam hold it need to this one and look at your lobes to see if its fatter or taller than the stock one. Other than that there is not really a way to tell just by looking at it.
