In between beers at your next bench racing session, and just for fun, check your cam specs, and see how they stack-up in tech author David Vizard's "Advertised Overlap Chart" below:

10* - 40* towing
30* - 60* ordinary street
50* - 75* street performance
70* - 90* street/strip
85* - 100* race
95* - 115* Pro race

Here's how you calculate your advertised overlap:

Add your intake and exhaust advertised duration (duration at .050 will not give you the correct overlap)
Divide that answer by 4
Subtract the lobe seperation angle (LSA) from that answer
Multiply that answer by 2, and you have it!

Now compare your adv overlap to the chart above, to see how wicked your cam really is. Most people think their cam is hotter than it really is, so don't feel bad if you are in that group, since you will not be alone. This can give you an idea of what to shoot for on your next rebuild

also post what cam it was
