Id say atleast a 1-2 grand. I mean it has some good work done to it but it is used and you never get what you paid for. Stock motors go for around 1k with those ammount of hours and good condition so Maybe start at like 1500-1800? There was another motor on here with alot more work than yours and he was only asking like under 1500 and still couldnt find a buyer if im not mistaken.
