As far as I know, the NAG-1 isn't even an option for the swap. I could be wrong but last I knew Nobody seems to have support for it. Like stated before you need to trick the transmission with sensors and stuff quite a bit with the factory ECU and there is NO aftermarket tune/control for it. There was a guy on here that tried with a 68 cuda and a SRT swap. He never got it to run/move last he posted a few yrs ago.
That's why everybody has used the 545rfe 2WD trans. I think that's the only way the factory ecu guys run a new trans. Which is also MASSIVE...
