not sure if these are worth anything. I removed from my '68 442 - the original motor had never been opened up. It died in 1986 due to freeze damage to the side of block. no signs of any rebuild or previous work- no bearing issues. Surface rust from sitting - easy clean up. I'll say $75 plus shipping - tell me if I'm stoned.
Thanks

 

One never knows what parts someone is looking for. Those caps are the same caps as a 455. Aline hone to the new block would be needed. Jmo.

 

I proved your point when I purchased a used toilet seat for my college apartment. The seller was amazed that anyone would respond to the ad and I was amazed to find such a great deal.
