You would spend all day or more getting it out.Then you would have $25 worth of s**** metal.Its not a rare engine or particularly desirable.Would cost exponentially more to fix than its worth.Sometimes you just have to walk away.
If you have never pulled an engine apart and done anything on the inside that one might be one you can practice on a bit but my experienced guess is that the inside will look just as bad or worse than the outside. But if you do pull it out of the car and take it apart all you are out is your time and you may have a bit of education out of the deal and you can haul it off for s**** after you are done with it if it isn't any good. I have to agree with 56don in that the expenses of fixing that engine will most likely be more than buying a rebuilder out of a junk yard and then going through it.
I removed a PowerGlide from a burned 70's Impala that had been fliped on it's roof for at least 20yrs, put it in my Cutl***, added some fluid, and drove it everyday for about two years untill I sold the car.
I brought home a Lark Wagon from Iowa last year that had been in the same spot for 14 years and didn't look even remotely close to that bad. It had a hood on it and the air cleaner. It still had anti-freeze that checked to 50 below! That has been there WAY longer than that and is probably home to a Badger or Timber Rattler. I "might" pop the intake off it since it's a 4 bbl. but the rest has become one with Mother Earth. This is what 14 years under an Oak tree in central Iowa looks like, the frame and floor pretty much disintegrated loading it.
i'm not rebuiling it or even taking it apart for him. he just want me to muscle it (and my chainsaw/truck)..i told him to find something else/buy my 429----but he is set on saving something from this thing......me and our other buddies have saved a car or two over the years and he want to join the club.....
That's nice.....I'll bet it still had a pan on it, though, didn't it? If it were like the 289 in the picture, with all of the tin long gone, and the valve body had been exposed to the elements for twenty years, I'm sure it would have been a real jewel.
or save the OT car he has sitting in his backyard under a cover......thinking i will run over by were this thing is and look around it....
