Early 70s 360 block

Hi, GTX John. Thank you for responding. I need a bit more info if you wouldn't mind.
Could I get the complete casting #?
Can you send some pics?
Has it ever been decked?
Thanks, James
3418915 is the casting number and this is the
ONLY number we have found to have the consistently thickest cylinder walls
in our testing.
It has not been decked ever.

After 60 plus years of Drag Racing on a National Level = I am aging out.
Otherwise I would not be selling this block that I have had forever.
I will post pictures in an Ad Tuesday if not sold by then.
