Raising shift points

Trailbeast, that is a great idea. i have been fighting kickdown problems. i had a 2 barrel on it and it worked ok but not the way i wanted it to. in other words, i had to really mash the pedal to kick it from 3rd to 2nd. i put a 4 barrel on it and i have the right linkage but i just cant get it dialed in . i still have to push the pedal really far down to get it to shift. i have tried adjusting it everywhere possible to the point that it wouldnt allow the secondaries to open all the way to where it was backed off, and everywhere in between. my question is this, what would happen if i were to just mount the kickdown rod solid to the throttle arm adjusted so there is about an 1/8 to 1/4 gap at WOT? would this work too?
