being dual purpose

on the topic of a dana

what about 4.10 dana gear running with A-518
(because that's the gear in the White Dart now.
1350 joints)
have a 3.54 gear but would have to narrow a housing.
don't want to change out the 4.10 vs 3.54

have a 518 (diesel) out of a pulling truck with good parts in it
5 pinion, hardened input shaft, billet drum, etc
could swap into the A-518??????

would the 3.54 be a better ratio ?

I know very little about setting up a turbo application
trying to learn.
