It could be alot of things Zack. Most likely its getting either too much fuel or not enough fuel when you snap open the throttle. Does it miss at higher rpm ranges? Have you checked the color of your spark plugs? Black - Gray - White? Most ignition problems occur at high rpms or all the time.

Is this a Chevette carb. Holley 500 or what? You can PM me if you don't want to post what kind it is. Sounds like the power valve might be too small. If it's a Chevette carb. and it's not been moved already, you might try moving the accelerator pump pin to the middle or bottom hole.
