727 -> 904

I'm also running the 166K Mopar perf torque converter due to cost restraints. Seems to work ok so far but I haven't ran it much yet. I have a buddy who has ran several with no problems and some of his cars have made over 400 hp. I did some checking and Guitar is right. They're just stock converters that they modify for more stall. But they're cheap. If you just have a mild build they should suit you fine.
