IT’S ALL BALL BEARINGS THESE DAYS
When checking volume on large chambers or ports, I fill them with precision steel ball bearings. It requires less time to fill and less fluid. Simply calculate the volume of the ball you’re using and multiply by the number added. Add that to the reading from your burette and you have the volume. Be sure to dry the bearings on a towel between tests. On many 100cc or larger chambers like Hemi and BBC, you only have to fill the burette once. It really speeds up the process on smaller chambers too. On large intake ports, you can use precision 1”x1” blocks of aluminum in addition to bearings.
