I have a Hemi with original magnesium cross-ram intake and new Holley cross-ram carbs. The car starts and idles perfect, good throttle response when car idle in park. The problem. If I give a quick jump of the throttle in gear it sometimes drops down to 600 rpm and comes back up to idle, most of the time it just falls off and stalls. Quick turn of the key and it restarts. What needs to be adjusted or looked at on the carbs to fix this problem? Idle mixture screws are all set at 1 1/2 turns out. Any input appreciated.
