With that cam and a 408, it should be a beast at low rpm.
8-3/4 is always a good idea but with the combo you have now. I would stick with a tall gear(3.23-2.76)
That stroker will give you all the grunt you need and good mileage to boot!
Now go back and reread J par post.
You may have a weak spring causing it to not rev......but i think it's just your combo, and i think it's the perfect daily/street cruiser.
keep this in mind. You will have a basic 2500 rpm line of power. Right now it's probably around 1500-4000 rpm. Put a big cam in it, hi flow heads intake and carb. Now you have a power line that don't start until 4000 rpm but will pull to 6500 rpm
With a street car i would take you combo, over that one, every day including Sunday
