Displacement is stamped into the flat machined area on the left front of the block, directly below the deck. ANY factory service manual will show this.

That spot cheif is talking about can be hard to read sometimes. It is just below the drivers cylinder head.

Other numbers are not behind the block, but on the drivers side of the block. The displacement is embosed there someplace. You should be able to see it easy.

Here is a link to what the balancers look like.

A quick way to tell is to look at the harmonic balancer. If it is counterweighted then it is a 360, if it completely symetrical then it is a 318.
