Another vote for 4.10.

Using Randy's Ring & Pinion RPM calculator (I'd say the slippage % is pretty low):

4.10 - 28" tire - 125mph = 6315 rpm
4.56 - 28" tire - 125mph = 7023 rpm

4.10 - 28" tire - 130mph = 6567 rpm
4.56 - 28" tire - 130mph = 7304 rpm

Your new engine probably has more RPM potential than I would feel confortable with using a semi-stock (internal pickup) oiling system. It will live a bunch longer if you keep the RPMs under 7000.
