My .02 on this,
3.73 with NO overdrive tranny would not be particularly good for highway cruising. At 75MPH, I was turning around 3400-3500RPM which I feel is too high.
With my current BB setup, R700 tranny and 3.73's I am turning @ 2500 at 75MPH (much nicer).
If I had a LT-1 or any "Non-stroked" small block for that matter, 4.11 and an overdrive tranny would be just about ideal. BB's don't need the 4.11's so 3.73's are fine here.
Remember also that LT1's LOVE alot of gearing. I would gear a 383 stroker the same way as a BB (3.73 with Overdrive).
The 302 is a different animal. Here I would go 4.56 gearing with OVERDRIVE because of the solid lift cam and the narrow power band 3500-7500.
