I've got a fresh 2F (~10K miles) stock 4 speed (H41 sitting on the garage floor...hopefully soon) 4.11's and 35" BFG's all under my highly aerodynamic 55.
On the interstate (flattish) I can run 75+ 2800 rpms, up the hills not soo much. It's not unbearable, but it's slow. :p I think 4.88's would be a lot to run on the highway. Too many RPM's.
Personally I would go with 4.56's if you are staying at 35's and a 4 speed. Above that I would go to 4.88's.
