30k !! ?? absurd !! what trans ? 727 or a 4 speed. Regardless, if he spent 30 grand he got hosed !! For ex: a 70 Challenger 440 sixpack, with a Mopar A883 18 spline 4- speed transmission & Dana 60 Rear Axle. .From Brewer Performance who specializes in Dodge rebuilt for $500 using your core. . A new rebuilt total replacement would be about $3000. Whoever told this guy $30k is super hosed. ( and that's a hemi trans at that)
