Patrick's has the 3.55's and what used to be Chevy Duty was offering some in the 3.30 range, a 3.38 I think. Something I find amazing is that a fellow with a farm equipment repair shop near me has a 57 with an overdrive and a 3.08 rear end. This is a final drive of 2.16!! We did some repair to it and when I drove it back to his place the route had some rolling hills and I was amazed that it didn't lug down even 1mph going up the hills. The 235 in it is fresh and runs very well but I'm still surprised that it pulled so effortlessly without bucking or pinging.
