Block Identification

[Khodabear]

just a naked block, no head, no pan, no crank ,no pistons.?
the 8v and 16v actual naked blocks are the same but not the pistons. the 16v had notched pistons, for the 4 valves per cylinder.

but if the block is really a short block ? complete, minus head , the pistons look like this.



new 8v

my issue is just a naked block -thanks also for the elaboration as it will come up again I'm sure :-)
