With the 3.73's you really won't need, (may not even want) that low gear set currently in the trans.
With it, it will sure be a head snapper, lol. It'll definitely tighten up the converter.
3.73's will however work real nice if you're planning an overdrive swap in the near future though. 4L80's with the 2.48 first gear works really well with 3.73's.
