4000 rpm's at 60, no 3rd?

That looks like a late model throttle rod setup, not the one a earlier A body should have.
I have the setup out of a 340 car and I'm pretty sure it's way different with a threaded rod on both ends so you have a LOT of adjustment.
Maybe you'll have to adjust it down on the tranny end to get what you need or try a different rod setup. I'll have to take a picture of what I have and post it, our Scamp uses a later setup too that is similar but doesn't have threads on both ends of the rod.
that almost looks like what was on my 72 satellite with a 318 and a TQ in it.
I'll get a few shots and post mine I guess.
