/6 swap to 360 questions???

Sounds like your pretty much good to go. I used a throttle cable from a V8 A body so IDK about the Lokar stuff. As mentioned the 2brl and 4brl kickdown is different, it can be modified but requires a welder and some spare parts. Have you verified that your /6 904 will bolt to the LA? I've always thought they did but I think I read something a while back that made it sound like they don't work, I'm not sure. You will probably need to get a flexplate depending on the balance of your motor and if the converter is balacned or if it's a neutral balance. Good luck
