I have a friend who has had a 4.6 V8 Northstar that he is trying to get rid of.
I came out of a '98 caddy and needs head gaskets.
It believe it has about 120K on it.
So if anyone needs and engine to play with or wants to fix it and sell it for a profit let me know.
PM me or just respond to this thread and I will get you in contact with my buddy.
