360 questions

I have a brand new, 0 mile 727 trans that I picked up to run behind the 360. It came out of a '72 van, complete with torque converter. I was thinking about just running it just the way it is, as suggested, and see how this "truck" drivetrain does in this car. I'm putting together a 8 1/4 Sure Grip rear with 3:73 gears.
