Camshaft Valve Timing Degrees Calculator

Find out your camshaft's valve timing events @ .050" lift by inputting intake & exhaust duration @ .050", LSA, and intake centerline. This calculator is useful for finding out your IVC @ .050" number when your cam is a brand like Comp Cams which typically only provides you with an IVC @ .006" number. Intake & exhaust duration @ .050" and LSA are commonly available on most camshaft sellers' websites (e.g. Summit Racing or Jegs). You can find out your intake centerline for your Comp Cams camshaft by searching its part # or grind # on the Comp Cams website and then finding your cam's specs page.
