Acording to this chart, rods # 16-51, are 2 step, are they not? Not trying to be argumentative, perhaps I'm not fully understanding how to use the chart?
I also cannot read the chart, but I believe GM used two-step rods in their AFB and AVS (yes, 1967 327 could be had with an AVS. I helped a friend of mine put it on his '57 283 back around 1980).
