Just remove the rod and have a look at it.
A good one will have the same length of metal "turned down" a bit on each
end (about 1/2" IIRC).
Worn ones will have one end a bit shorter.
And don't forget that the worn end of the rod will often wear away on the
camshaft lobe too, so even a new one would be "short" and you would need
another cam.

Subject: IML: Fuel Delivery Problem
> The fuel pump on big block Mopars is driven by a short push rod. Over the
years, this rod becomes worn and eventually results in poor performance of
the mechanical fuel pump. I checked the 1964 Manual and couldn't find a spec
for the rod so I'm reduced to identifying a possible problem while lacking
the ability to define it.
