BBC vs Ford Rocker arms (1.70 1.71 respectively )
text and photos blizzND
On real cold North Dakota night I went out and photographed these 2 Harland Sharp rocker arms, as a discussion about the differences was raging on the forum.
The photos are not the best, but you get the point. Also, I have a decimal place in the wrong spot on the .098 and .095 measurement, it should read .98 and .95 , they were measured with a machinist scale and probably not the most accurate, but close enough for this illustration.
