Hi All,
I am looking at buying a used bare engine block. Just like to know what to look out for? Obviously bore size but what else?

Thanks

1. Cracks between the bores at the top deck. Not common but does happen.

2. Check the 3 main caps are original, best done by measuring diameter but a fingernail on the joints will usually show if they don't belong.
Caps were line bored with the block originally.
A block with no caps = a doorstop (unless you want to pay for a set of new steel ones and a line bore job).
