Car shuts off when put in drive

looking back, i think my 1407 was too much carb and the holley 600 was a perfect cfm for the engine. i have a few 1405s,06s and the 07, i think i am going to give one of the smaller ones another shot. the holley has been pretty good , but it is very tempermental, especially when it is hot, and it is a little more of pain to get dialed in.
