I have the 355 and wish I had followed my own advice

There is a BIG difference with 3.55s in the EB vs 3.55s in the 5.0 or the 5.4 like smurf has. My work truck 5.0L 3.55 Scab is a dog compared to my personal EB 3.55 4x4 Screw until it gets past 3k rpm or at WOT. I have to mash the accelerator down a quite a bit more on my work truck to get the same kind of everyday driving acceleration compared to my EB. I can really tell the difference if I haven't drove my work truck to go see customers for a long while and then use it again. I don't know what it is, but it just does not have that barely touch the accelerator and go power that my EB has.

i test drove a couple 5.0 with both sets. the 3.73 felt a little "faster" and more effortless. they were both good though and i'd probably be happy with either one.

After getting the Eco in 3.73 after testing 3.31 gears I would never get anything but 3.73. Fuel economy is same as my 5.0 3.55.
