Which rear gears to get???? 3.42 OR 3.55

[turbopowered68]

its a heavy car @3800#
i just bought a 12 bolt rear and i NEED Gears as the 3.31s in it has a few bad teeth.
my NEW as in available "Brand new" gear selection is 3.08 (not going to happen) 3.42, 3.55 and numerically higher.
So this narrows it down for me to 3.42 or 3.55?????
Which one would you get??

BTW NOT going to lock the Converter at WOT.
the converter is a 9 or 9.5 3000 LU from ProTorque.
thanks for your help
