Hi guys I am in the mix of getting a fully forged BGE 6.4 together to replace the 440 that is in my Dart. My goal is to get it running NA and then once that is sorted out I want to fab up a turbo kit for it. Right now I am torn on that transmission to use as I eventually want to be in the 800-1000hp range once the chassis is sorted out. I want it to be reliable and streetable. It will be 50/50, race/street. I have a powerglide,th400 and 727 in the garage. Which one would you guys choose and why? Thanks!
