Shit, that sucks to hear, failing a new donk, is it possible to source just the cast block? New pistons and rings shouldn't be too exy. And you could reuse most other parts from your engine.
If you had the liquid funds, (which I kinda gather you don't) you could chuck a stroker kit in this (with refurbed cast block) and have one heck of a car..

Once more, sorry to hear this sad news.. :-(

Keep us posted.
