Casting 25506397


This casting appears to be a RWD 1983 3.8L from a Riviera according to

It is a "turbo" block and still has the turbo attached with heads and such.

Are these significantly different from say the 84-85, 86-87 3.8's that were in Regals? It is local to me and cheap. There isn't much info on gnttype about it other than this...
I wait for the day people want to use these blocks. I have a few sitting in the way at the machine shop....
