It depends if you want to invest time and effort into stripping it down. The block may be savable, as might most pieces. There will always be things like starter, pan, flywheel and clutch that are all useful. It's impossible to say what you might want to save off your seized motor if "seized motor" is all the description we have to work from.
If you don't want it, you ought to at least offer it up to someone that might want to invest the time and effort to salvage whatever is salvageable.
If you lived near me I'd take it off your hands.
