904 misbehavin'

The 2 bbl rod is indeed shorter than the 4 bbl rod. If you have a 2 bbl rod, you probably won't be able to adjust it far enough.

I went through this when converting my car to 4 bbl. I think this post will help you.

Thanks, 65. That's a good thread all the way through. The part your link goes to shows what I call the basic blacksmith technique - and it works quite well, as you proved.
I have the Edelbrock "linkage stretcher" part #8004, the NON blacksmith method. Looks like it will solve the problem.

(EDIT) A late Christmas present for me!! I found another length adjustment at the top of the rod that goes down from the upper to the lower bellcrank.
Cranked on it a bit and found that the back end of the slot at the end of the upper rod was very close to the carb throttle stud.
Minor adjustment of the slotted end piece of the upper rod, and now the upper rod starts to move to the rear at the same time as the throttle stud. (YAY!!)

I'd be test driving it now, but the voltage regulator bolts turned out to be stripped and I need some bigger bolts to ground the regulator case to the firewall.
Like the late lamented Roseanne Rosannadanna said "It's always something."
