From the information provided, its worth somewhere between $50 and $2000.

Seriously,
IS IT RUNNING?
Was it rebuilt recently?
By Whom?
What features?
What is the compression at each cylinder?
How many miles on it?

Answers to those questions might provide more informed answers.

They don't run, I bought both of them with a model A sulfer machine. The Replacement was stuck when I got it, the other was spinning free until this year when it got rain in through the water neck I think, and now there is surface rust on the piston and cylinder wall. Basically their long blocks.

Are they standard bore or 125 over (should be stamped on top of pistons)? Also general location, middle of Los Angeles or middle of Nevada?

I have come home to find engines laying in front of the garage ---5 or 6 have appeared that way, I didn't want them bad enough to go pick them up , at Hershey this year I bought a short block---it was up the aisle from where I was staying, every time I walked by it called me, looked at it several times, std pistons, no signs of cracks,clean not rusty water jacket- 90$, --when I got it home and apart-still had original centerlock pistons,cam bores in middle of standard specs, machining marks still there ---A person that is just starting to hoard will pay more, a hoarder that is starting to think he has too many will wait till you will deliver them.

The head is off on one, I'll check the piston.

All I could find on the pistons were 40 and some letters like front or something like that.

Lodi I am just down Hi-way 99 from you in Manteca. Your block is bore .40 over and front means that part of the piston points to the front of the block. I am looking for a good long block but can't go over $150.00. So PM me your phone number and may be I can come and take a look at it. If you are interested. Richard/ Manteca

Now that's funny!
I felt like a "hoarder" when my dad brought down a spare engine. "Who has a spare engine?", I thought. "Spare water pump, maybe, but a spare engine?"

Sorry, had to jump in.
Now, back to the sale.

I have spare engines for all of my old vehicles-there's a flathead Chrysler 6 out in the pole barn, along with a flathead "Go Devil" Willys jeep engine, and three Model A engines. I like to accumulate "castings"-the parts that often aren't repopped. I'll always grab a good manifold or a transmission,especially if it is cheap. The Dodge engine was $25 at a farm auction-no one else wanted it, and they put it in the back of my truck with a front-end loader-How could I say no?

One member of the club gets $500.00 for a block. He does not guarantee anything. If it is no good come back and buy another one for $500.00. I gave two engines away recently to club members and they were good engines- no cracks and the bearings were good. I wished I would have taken them apart and looked at them. Two or three members said I messed up. The two that I gave the engines to always say thanks and I hear them mention my name when showing off their running engines. I do not think I will need them and I would just let them lay around for ten more years and they would probably be hauled to the scrap yard by some family member.

Wow, that's great! You didn't "mess up", that's just covetousness talking in those members who didn't get a free engine. A good name (as you are spoken well of by your benefactors) is more precious than gold.
