 ====== Pushrods ======
-Pushrod lean angle on 91-up engines.
-The lifters are square to the lifter bore but they're not quite square to the rocker arm slot for the pushrod. \\
-There is a slight lean angle between the lifters and the rocker arms as shown below. \\
-The pushrod tubes line up square with the lifter blocks and hide the lean angle of the pushrods. \\
-In the pics below, a inside bore gauge is lined up app. straight from the lifter bore to the rocker arm slot for the pushrod. \\
-This is the app. lean angle of the pushrods between the lifter and the rocker arm. \\
-The pushrod angle also changes as the rocker arm moves thru it's arc while the valve is opened and closed. ((Tomcatt of the XLFORUM http://xlforum.net/forums/showthread.php?t=2074861&page=3)) \\
