So would I...I'd buy it.
My brother would buy that. He loves himself a good 390. His first Mustang came with a 390.
just so you know......the 390's that came in trucks were different engines than the ones for cars. the block was the same, but the heads were different and the performance is very different and apparently the trannys had a different bolt pattern. so says a co-worker who has a '66 fairlane with a 390 truck motor in it. he got it that way, and has all kinds of trouble with it. not so much the engine itself, but all the stuff bolted to it.
