If you're looking to get a blower, then 4.10's wont be high enough.

you will absolutly notice the difference in gear between 3.90 and 3.73.... I personally think the 4.10 is a useless gear. if the 3.73 isn't enough for you, and you don't think the 3.90 will be, get a 4.30. If youplan on a blower in the future, don't touch the gear.

I have driven cars with all the different gears in them. For the record... 5.0 doesn't make gears (that I know of, never heard that before)... Motive, FRPP and Richmond. Motive makes Ford gears anyway, and the SCT Xcal2 is available to make the speedo calibration.
5.0 does make gears, but they are made of a much harder metal and tend to be noisy because of it.

4.10's are still a waste of gear.... 3.73, 3.90 or 4.30... The reason I don't like 4.10's are because they're not fast enough for N/A, and they're to fast for a blower...

Didn't know that 5.0 made gears... learn somethin new everyday.
