I wouldnt jump on it for that price. Honestly (at least in my area) These motors are worth nothing. I had my parts truck running, (ran like a TOP) SUPPOSEDLY its a turbo spec still have no idea how to prove it, but it was a brand new longblock installed in 07, with receipts. The highest cash ready to go offer I got which was for the motor, all accessories, radiator, AND rv torque converter was $350.

I figured if thats all these are going for I will keep it as a spare, as mine has 310k on it; and just the ease of having spare accessories ALONE is worth more then $350 to me. GRANTED I live in Tucson where money simply doesnt exist right now.
He either actually wants it gone and is willing to let it go for like $400-$500, or he is extremely proud of it and wont. If you cant pick it up real cheap too risky imo.
