what year block is this? what are the differences between the years... the crank looks to be forged as their are no casting marks.

here are some pictures:
castings (http://i8.photobucket.com/albums/a38/99mustang232/99_ford_mustang_232/IMG_0575.jpg), timing (http://i8.photobucket.com/albums/a38/99mustang232/99_ford_mustang_232/IMG_0561.jpg), block + crank (http://i8.photobucket.com/albums/a38/99mustang232/99_ford_mustang_232/IMG_0589.jpg), rear main (http://i8.photobucket.com/albums/a38/99mustang232/99_ford_mustang_232/IMG_0563.jpg), main (http://i8.photobucket.com/albums/a38/99mustang232/99_ford_mustang_232/IMG_0567.jpg), bottom end (http://i8.photobucket.com/albums/a38/99mustang232/99_ford_mustang_232/IMG_0589.jpg)

89-93 all blocks are the same, as long as it has SC on it then its a SC block of course, i think early 89 SCs had a DURACAST crank i dont know anymore from that,

94-95 SCs have differenct cooling jackets and different coolant ports were the heads connect...

Should be an 89-93 block since it does not appear to have the correct studs for the windage tray that came on the 94-95 engines.

the rear main cap says E9S ECA so I am told it is a '89, did some of the '89s come with forged cranks?

They don't update the casting number every year so that block could be anywhere from 89-93. Most of the 89's came with forged cranks. Only the very early production SC's got the cast crank. Frankly I've never seen one. You can check the parting line on the crank. If it is very thin and sharp it is cast. If it is wide and rougher looking then it is forged.
