I have the same tranny in my 68 Barracuda. One question I have for you did you cut off the boss on the front shifter mount or dent the torsion bar cross member for clearance?

On mine the tranny didn't touch when I mocked it up but driving down the road at certain speeds it would and that made all sorts of noises that drove me nuts for a couple of weeks before I tracked it down. I cut the boss off.

I have a stout 360 infront of mine with 3.55 gears out back. I seldom use 4th gear unless I am on the highway because of the lugging issue Krabysniper mentioned. These trannies are noisey if you start loading and unloading the gears.
