Ron, some differences in what I found:
Major engine specs are
.......................................2.0........ .2.3 Early....2.3 
Late.....2.5
Bore...............................3.520........3. 
780.........3.780......3.780
Stroke............................3.126........3.1 
26.........3.126......3.401
Bore Spacing...................4.173........4.173...... ...4.173......4.173
Main Journal Dia..............2.3986......2.3986.......2.2055.. ....2.2055
Rod Journal Dia...............2.0468......2.0468.......2.0468. ....2.0468
Con. Rod Length..............5.2047......5.2047.......5.204 7.....5.457
Crank Center to deck.......8.368........8.368.........8.368......8 .368
Piston pin height...............1.583........1.583.........1. 
583.....1.2105

I am liking the late 2.3 specs.  I need to look at the head /valve 
layout and heck, maybe a high compression piston for a 0.020 or 0.030 
over bore would work in the HIPO 260. The rods are almost perfect 
length.  Maybe turn the 260 crank journals down by 0.030 and might be 
close to working.  Might be more pistons available for the 2.3 motor 
than for the 260 for sure. Since I have o have the crank re nitrided 
maybe turning it down to the 2.3 rod journal size is a doable thing 
also.  I need to go see my motor machinist... Next is finding out what 
the thickness of the rods are at the big end.

I need to do more research.
