This relationship is often referred to as the valve train geometry. On many OHV engines (like Chevy V8s) the geometry is adjusted by changing the length of the pushrod. A large number of variables are involved in determining the correct length pushrod for your application. Pushrod length is affected by any of the following: |

| + | Note: While opinions vary, many agree a centered pattern is ''less'' important in many cases than a narrow swept area, as long as the rocker tip is in no danger of riding off the edge of the valve tip. It is strongly suggested the subject of valve train geometry be researched until the builder is satisfied with their decisions. | ||
