Engine Hesitates and Dies - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bought a 68 C10 LWB with a 396. It ran a little rough when I got it and tried to tune the carb (old q-jet) and found that it had a large vacuum leak. The truck did run and drive ok though. I replaced the q-jet with a 1406 Edlebrock and got it tuned in good. Now when I drive it hesitates and dies when I accelerate. It does better if I punch the gas. When it is parked it idles great and I can hit the gas then (in park) and no problem. Any ideas?
