904 Manual Body for Street

Am I going to get too harsh of shifts if I go to a manual body, eliminating the carb linkage which controls pressure in the trans? My 71 Dart with 408 and pushing 500 hp will be driven mainly on the street. I would rather not deal with the extra linkage and adjustments.

some info...

3200 lbs with me
3500 stall
Kolene Steels, Red Altos, bolt in sprag

Thanks!!!
