i All,
I'm going to be listing these items, but I'm not sure what they're worth. Any help would be appreciated.

455 olds "F" block, iron crank, and a pair of heads.

 

Does the block have its main caps with it? What do the cylinders look like?

 

No main caps, I'll take pictures of the cylinders

 

Then the block is basically worthless.

 

I have been trying to sell a 455 block, 30 over, clean as a whistle, bagged and can’t get 250.00 for it..a guy offered me 200, I said come get it..but shipping costs prohibit the sale..shipping has ruined selling engine blocks unless it’s a rare block. That crank is rusted, who knows what it will take to clean it up. Best to you

 

I think if someone wanted to do build it all could be saved, if the crank cleans up , etc.

Main caps can be bought, everything made correct.
How much time you want to put into it ?
Those look like Ga heads, possible 2.07" in with big exhaust valve 1.685" that'll do anything any other iron Olds head will if you put the effort in.

Find someone close by , always a shame to let it go for scrap.
