Stated- " But what we are most proud of (other than their power producing potential) is the lack of pushrod tubes ...."
Interesting subject, removing material from the pushrod bulge and brought up within this thread:

A factor or not, I'm not sure. But I've always enjoyed Jim McFarland's comment regarding mixture homogeneity possibly involving a protruding pushrod sleeve.....
A train comprised of loaded cattle cars is moving down its tracks at a constant speed. In this example, the train is analogous to air and the cattle to fuel. At this point, the combination is well "mixed". Now, visualize what happens if the train suddenly changes in speed, direction or accelerates or decelerates. It doesn't require much imagination to realize how the quality of this "mixture" will be effected, accordingly. Such is the case between air and fuel in an inlet path, during changes in air direction or speed.
