The FE or FT series engines were good units that will run a long time if treated right.
Rust in the cylinders, if not badly pitted, they should clean up with a hone IF the cylinders are not worn out. Was the "rebuild" more than a ring job on worn cylinders or was it rebored or re ringed with good stock bores?

Grind the crank ? Check it out, if it measures within normal specs,it aint broke and don't need fixing. If it's worn beyond normal specs, then it needs to be reground to the next undersize or exchanged for a reground crank with matching bearings.
Do it for $1200 ? You can do a lot with little money if you choose well from used/swap meet/Ebay parts. The cam,lifters and valve springs need to be a NEW matched set from one company, and broken in as recommended by the cam builder. Stay conservative and realistic with the cam specs,something that pulls good in the 1500-5000 rpm range, thats where you will be running a relativly stock 390.
