Installing two Holleys on tunnel ram......the little tab that sticks out on the left needs to come off in order for the throttle rod to work both carbs, should I try to bend it straight or just saw it off?

might as well cut it off , if you bent it straight and then some day bend it back it'll break off anyway. you'll never need it.

Six of one, half dozen of another. I'd bend it personally, but it doesn't matter. It must be there for something, but I've never seen a car/motor that used that little tab.
An engine that might have run on when shut off uses a solenoid to replace the idle screw. When power is removed, the throttle plated will close completely and eliminate the run-on as air is sealed off. The tab happens to be a great place for it to hit the solenoid.
You would usually use the large hole with a bushing, and place the rod assy on the inside of the lever, towards the carb. My friend runs nothing but multi-carb setups, and I have never seen him remove the tab.

Good point. I'm not sure which motor though. 750 vac secondary carbs (3310) have that loop, but not that tab
The only place I have seen it is on cars with AC to set an increased idle when the AC is in use (Chryslers come to mind). I used it on my 426w dual quad as I had a run-on condition.

Yes, that's what I was thinking when I did a test assembly with the rod on the inside, however, the screw that holds the rod to the bushing is also on the inside and you can't tighten it.
saw it off I'm running 2 holleys on my x-ram and had to saw off the small tab at the bottom
