Carb throttle return spring.

 

Check your application though, as not all Big Blocks with the alternator using that bracket had the throttle return spring attached to this bracket in the front. My '67 L78 had the return spring attach to the coil bracket behind the carb.

 

I removed the tab. Didn't see a use for it. If that's for a throttle spring it would be a crazy long spring.

 

Yes, it was the "green spring" and I've seen some engines with that setup. But, I think it's dumb with the factory pcv line that crosses in front of the engine which conflicts with the spring. Maybe only the high performance 396's had the spring connected to the coil bracket? Another interesting trivia item!!!

How did you remove your bracket?...just heat it up? I need to remove mine before taking everything to the engine builder. I'll just repaint the upper bracket.

 

1966 used the extra tab, 1967 didn't. I think both versions are available.

 

Thanks Bruce, but I'm yet to see a repro one without that bracket attached (like the one I bought from Ground Up...so it goes!)...I may just cut it off, as like was said, you won't see it anyway behind the coolant hose.

 

 

Once again thanks to everyone for the learning lesson. I ground the tang down and removed it then sanded so you cant tell it was ever there> I appreciate the help!

 

Nice job! I actually found a better repro one (Auth GM Repro) and it's slightly different , nice "heavy" steel and no extra tab. Now I have one left over, but what else is new? I didn't think I'd be able to remove the entire tab like you did.
