Olds 425
Anyone looking for a olds 425, has been setting long time , will need complete rebuild, motor would not turn over 3 years ago. asking 400 but if someone on here can use it 250.00 will take it. But you must be able to pick it up in Decatur Indiana 46733.

I took it out of 67 or 68 toro, I could not remember year for sure, it ran when I pulled it, that was 13 years ago. 3 years ago I tried to turn it over and it would not turn, I took plugs out and filled it with transmission fluid, but have not tried to turn it over since then, motor is buried over in corner of garage, pics where taken years ago.

C heads with big valves, large lifter 425 39 degree cam would make it a 67. Should be a D letter on block to confirm the 425. If rings are stuck no problem just so the block is not damaged from catastrophic failure. Could be spun bearing as well.
Just saw you said it ran so should be fine with just some stuck rings, sweet deal for someone!!

Not much room to work around motor, tried to turn over with 1 1/8 socket and ratchet , but motor wanted to rotate off engine dolly , so I stopped, still will not turn by hand. There are C on both heads, and a large D after stamp numbers.

That's ok, I know shipping is high. If no one buys it, I'll just keep it in corner of garage for another 13 years! It's not costing me anything to feed. Just thought if someone could use it, that's better then setting here and doing nothing with it.

It doesn't turn for a reason. I wouldn't force anything with those cast pistons in there. You'll break the ring lands. The offending cylinder(s) must be identified, rotated downward, and cleaned up enough to clear the blockage.
I wish you were a bit closer, I'd play with it and get it running again just for kicks. 10 hours on the road for the ol' lump is a bit out of my ambition range at this current moment however. Those are great motors.

Not trying to derail your thread, but I'm curious what the pros/cons are re: using this 425 instead of some unnamed 455 if I wanted to do a BBO swap for a mild street build. Seems like a great engine to rebuild, especially for the asking price. I do see that it is 40 lbs heavier than a 455 (442.com) which surprises me (does one quart of oil weigh that much?), and I suppose the lifters might present a problem. Are parts for this engine tough to find/prohibitively expensive to make it not worth it unless I was doing a restore and needed a 425? Are there any threads on this? Thanks and bump.

The only cons that worry some is 30 cubic inches. It has a forged crankshaft which is a plus, shorter stroke, and larger more expensive valve lifters. It should have large valve heads. The factory Toro intake was a low profile design and probably not the best. The cam angle is 39 degree which make cam selection quicker. For a street build I would jump on it!

Still long drive
Well only 8 hours from me still a haul when only have one day a week off you ever come to Memphis TN bring it with you I will buy it. Just a thought if you are ever close to this area?

Locked up doesn't bother me just like most too far to drive to pick it up. You have potential of a pretty good engine. Pull heads see if you have build up above pistons. Or of lower end problem with heads off you should be able to tell. But as I said you ever make road trip through Memphis Tn bring it with you and I will take it off your hands
