Re: Freiburger, DCR, and testing.....
It's going to vary with different engines, but really how much does a piston move in the time it takes for the valve to move that .050"? I'm guessing it's neglegable, but some one more familiar with engine geometries than me would have to do the calculation. I'm guessing it couldn't be more than a one cubic inch (On a SBC 350 4" bore that's ~.08" of the stroke or about 2% of the stroke)
