I am not very good with motor and I need your help, I have 383 motor with 4 speed and it already rebuild. The problem is:

1) Holly carb - which ID # should I used? I want new one, can I use 4150? Double Pump or Elec?

2) My Intake with choke stat but it was same level as barrel level so it hit the carb. So I need to raise carb higher (use Carb Spacer 1" or 2" raise)

3) If I used Carb Spacer and I have air grabber hood and will it hit under my hood when I closed it?
