A-904 Throttle Pressure Adjustment

Way late, but like ALL my questions have been answered reading through these old posts...
72 duster, was originally a 318 car and I put a 360 in it still a stock 360 from 1974 and it hooked up in every gear until it goes to shift into third under hard acceleration it's almost like it kicks into neutral unless you leave off the pedal and then it's there in third gear even when you stand on the four barrel...
So I plan to rebuild a separate 904 I have sitting here most likely with the trans go/trans star kit and I feel confident I can do this well...
I would just like to ask, with no kickdown lever on to the carburetor but still set up to the transmission and pulled up all the way as if it was at idle speed would it shift the same way and slip going into third?
