What would a.big block 7781 be for http://www.yenko.net/ubbthreads/pics/usergals/2016/03/full-1102-40982-imag0655.jpg

From what I found that is a very desirable Pontiac starter. One of the easiest ways I tell small block from big block is by the size of the neck down. Big blocks have a much less pronounced size reduction on the main case from that of a small block. Here is a big block vs a small block.
