In my car that I am building it has a manual transmission and I will be coasting in neutral or with the clutch despressed. But with my SHO, I decided the gain wasn't worth the chance of damaging the tranny.

We had this same discussion in another thread and it's good to see that I'm not the only one advising against it. The potentially damaging action comes not from coasting in neutral, but from when you shift it back into drive. I recently stopped by my local Aamco shop and asked this specific question. They told me the same: don't do it.
What you can do safely however is to coast in neutral to a stop, as when you are approaching a stop sign. On local streets in neighborhoods that have a stop sign at every corner this can increase FE. As long as the vehicle speed is zero (or at least under 10 mph) the A/T will go into first gear when you shift back into drive and it won't harm anything.
