66 C10 stalling

I own a 1966 C10 with a 327 that will stall when I accelerate too quickly, either from a stop or while driving down the road.
If I accelerate very, very slowly it runs fine.
Could this be a carb or timing issue?

 

Yes it could be either or both. Check timing first then make sure your secondaries are operating properly when you go wide open throttle.

 

Thanks drabo, I will try that.

Could also be a vacuum leak

 

accelerator pump ?

 

If none of those work check the fuel pressure at the carb - possible kink or restriction of the fuel line starving the carb.
