Suggestions are kinda hard to give about what to do, that kinda depends on your own taste but i can tell ya that the 390 did respond very well to a nice torque cam and intake/exhust change.

Theres a couple good places for parts also, the birds nest is one and the T-bird ranch is the other.....also Pat wilsons T-bird parts has some nice orig. parts for a decent price.

Sounds like your gettin a low mile bird thats great let me know how it is when ya get it.
