i will double check the iac, i am using a 454 tbi, but i believe i used the iac from a 350 tbi.....checked the wiring three times, but probably should do it again.... i would think that if it was wired wrong the 7747 would have had problems with it as well though. would the 454 bin make a difference here? i was aware of the wiring difference between the 454 iac and the rest, but thought that the difference was all wiring/hardware, not in the .bin.......
