doing all that it has no choice but too work, I would think.. keep us posted on your progress, if you use the limited tranny and tcm you can run the 327 rear i think, otherwise change rear, tranny, and tcm.
as you have read i tried to use the 327 with the srt 6 tranny and tcm (did not work) also tried to reprogram the tcm to the limited (did not work), had to use srt tranny srt tcm srt rear (307),, let us know jim
