Is there any demand for Big Block 727 Transmission cores?

[Topcat]

I was at a transmission parts place today and they probably had at least 15 or 20...maybe more, big block 727 A/T transmissions.

Bunch of work sorting thru them their numbers on them.

What kind of demand, and what are cores typically worth?

Core buying market goes up and down all the time. Currently $40 - $75 depending. Now keep in mind this is "core buyer" price, not what they would sell one for. But I doubt that's a real strong market anyway. Unless you got that "one" for that numbers guy....

I've found the 727 part numbers in most demand for the "numbers matching" guys are for the 1970 model year. 
They are:
- PK3410670 for a 440 4bbl car
- PK3410671 for a 426 Hemi car
- PK3410672 for a 440 6bbl car
I've seen cores with those part numbers go for $1000 on the low end and $4000 on the high end for the Hemi number.  Of course, the partial VIN stamp will not be numbers matching.  Attempts are made to get as close a possible to their car build date with the stamped 10,000 day calendar 727 assembly date.  It's as close as one can get for a correct transmission.  I suspect there will be comments about how nuts the numbers guys are.  I'm just stating my observations.

I agree, 70 units seem to bring the most, but any muscle era automatic trans will have more value than one out of, say a 74 station wagon. One of my Challengers lost its original trans back in the day, someone had put in a 67 440 unit, after I ran the numbers and put it on craigslist it sold quickly to a local guy restoring a 67 GTX. I also had an extra 70 383 auto, (3410668 would be one to add to the above list) it went from me in NJ all the way to the west coast, the buyer paid a fair price for it and then probably also at least that much more to have it shipped there.

I like picking up the 4 pin planetaries etc. So yes I sure wouldn't through a BB core away and I like the HD units just fine.

Couple years ago I helped a friend with his 70 Charger and we dropped the original numbers matching transmission off at a local shop that came highly recommended. I mentioned to the owner that it was imperative we received the same numbers matching unit back rather than a core he already had in his shop. He laughed and said it wasn't a problem because he hadn't had an old 727 in the shop in ten years so there was no need for him to stock cores for faster turn around. Happy ending...we got the original back and it worked awesome.
