During the restoration of my car i decided to add some power to it as well. I have a 383 with adding the power package from edelbrock. With a Thunder series 800CFM Carb.... all brand new.! Car starts up fine and idles fine in park. Automatic transmission. Once i put it in gear it bounces around. At higher RPMS it seems to be very responsive. If i was to punch it out of the whole it wants to fall on its face before it goes. I and several other mechanics have made several adjustments to carb with barely any results. To narrow it down its a rough idle in drive and have to ease into it to get it going. can anyone help me with any sugestions? anyone local to me that would like to look at it? Before the upgrade i could slam the pedal as fast as i wanted to and it would jump and go. I miss that!
