CayoRV,
I suggest calculating an ideal using knowns and unknowns.
For instance cruising speed (mine was calced on 70 mph), tire height (mine 31"), optimum engine RPM (about 3200 as a guess - someone will chime in on this for your 235), O.D. ratio of .63 (this is a given and won't change). Unknown or variable will be rear gear ratio. Plug in the 2.73 to start and change tire heights (usually the cheapest and easiest change for the buck)and gear ratios to get the opimum engine RPM at top speed (i.e. 70 mph).
There is a link to a calulator on the links page of this site.
My guess - 2.73 will lug her down. Mine calculated to 3:90.
