The 4.11 ratio was never a problem for me, even with the stock 3spd. I knew that the 302 was perfectly capable, and happy (if not exactly at it's most efficient?) to run in a higher rpm range. Never gave it a moment's worry as far as the engine itself was concerned.
With the old 1:1 ratio and 32" tires, I was happily cruising anywhere between 55 & 75 mph.
Hovering around 3200 rpm or so was not an issue. And seemed much less stressful when I put a quieter exhaust on too. Exhaust sound has a huge effect on perceived rpm, and the engine's happiness at said rpm.
With the slightly taller 33x11.50's, it was a little better. Right now, it's still apart waiting for the NV3550 to magically install itself!
With the stock engine, I don't think the 4.11's will be quite low enough however, since overdrive with the larger tires could still put me in an unhappily low rpm range. However, with a properly tuned and running engine, with a cam that's happy creating torque in the proper range, I think the gears will still be perfect. Even exceptable with 35's.
That's the ultimate dilemma though. With the 35's and a good running engine, will the 4.11 still be good in overdrive with the 302, or would the extra few hundred rpm of 4.56's, or even 4.88's, be better?
Time will tell.
