I conducted more tests at high speeds last night. Now, with about 2 hours break in on each, and at 32 scale mph the engines pull apart within a few minutes; after 10-15 minutes the faster one is a good 7-8 feet ahead of the slower one. I am hesitant to lash these two engines together. The faster one would not only be pulling the heavy consist but it would also be pushing the slower one...

You're making mountains out of molehills! At 30 scale MPH for 10 minutes, you have traveled around 550 feet. You're talking less than 2% speed variation between the two engines! That's actually very good, and you can't expect it to be a lot better than that. These two will have no problem being MU'ed.
