general v8 question

[this is not cbring]

i've located a rebuilt 400 from a 69 gto along with rear-end............now i'm looking for a tranny.........

i live in an aparment complex and park on the street, so doing it myself isn't really feasible.................i'd planned on something turnkey, but not every day you get a deal on a 1970 tempest.......

also Rev, 1970 is a few years before smog era
