COPO 427 BBC block Whats it Worth?????
 

can anyone tell me what a casting # 3963512 COPO block is worth?

What is the casting date?

1969 427 two or four bolt main
or
70-76 454 two or four bolt.

If it's the 69, it may be worth something for restorers. Dave

according to this it could be a 427 or a 454...with 2 or 4 bolt mains...from '69-'76....same question as Old asked you....

I sold 2 3963512 blocks on EBAY in the last 6 months. One was a L-19-9 dated (December 1969) 2 bolt main LS-5 454. It was .030 over and had damage from a roller lifter breaking...I got $987 for that one.
The other was a December 18 1968 block..It was a 4 bolt main 427. It was bored .060 over, had one hole that needed a sleeve. I got $850.00 for that one. It is ALL about the date codes. If you find a guy that has a car that needs that block then it is worth whatever he is willing to pay.
