Salvagable Block?

Best-case - leave it alone until you have ALL the money for an engine. Then have it machined, assemble it, and get it running. It's totally pissing money away to machine or clean it, then leave it anywhere. Even my heated garage will generate some rust over years of sitting. If you can't afford doing it all, wait until you can. If you have to do the body - do that first.

Ok...I admit I am not an expert. Machine work on the motors I have been doing is well over a grand. I wouldn't even think of messing with it until you are ready. Stroker components aren't cheap. Spending all that dough then taking a chance while it sits is riskier than keeping it dry in my book.
