I think with the 3.38s you will be fine. If not you will at least be better until you can make it fine. Mine must be 4.03 low and it's a little low with the 3.55 rear end but comes in handy on the steep parts of my road with a load. Not like a "Granny" gear but low. You'll get used to it.

"I wonder if God created man because he was disappointed in the monkey?" Mark Twain
