need info on 82 crew cab dually

[CBot]

I sadly just sold my 1985 chevy silverado shortbed. but hey i made money on it.

i have ran across this dually here. ill post the link and pic. I have never dealt with a dually. guy says it could be a daily driver. 366 big block? doesnt seem to be a factory engine so idk what to make of that. any info could help. it is missing the back seat. is this guy asking a fair price? how much should i offer him? he is offereng a set of steelies if i dont want it with the alcoas.
