Not sure about the 1970 390, or the 1975 360, but for 1969 the truck engines were 215bhp (360) and 255bhp (390).
Not positive, but I believe the 360 dropped to 205 bhp after `71, and again dropped to 185bhp by the end of it's life in `76.
Also don't have torque specs handy, or I'ld post those for you.
Best bet is to build an engine the way you want it, as any used engine, regardless of what it came in originally, is going to produce less than it's supposed to, due to wear and age. It's also a crapshoot no matter what you do, because who knows what is inside the engine after 27+ years!
On another note, if you can get a good running 390 at a decent price, you'll be much happier with the torque and hp available over the 360 or 352. Just make sure to verify that it IS a 390, and not a 360, or you'll be unpleasantly P.O.'d at someone, most likely yourself!
