I have a M44 engine that has 150k miles on it. I pulled it to put an S52 in my car, and I can't ever seem to get it back from the paint shop
. It runs great and I never had any problems with it. It doesn't leak any fluids. It also came out of an automatic so you know it hasn't been over reved or anything like that. $600 and and frieght shipping and its yours.
