One more option: ship (flatbed) the vehicle to OTRAMM in Northern Virginia (~300 miles depending where in LI you're located). If you have triple AAA you might be able to get it 2/3 of the way there on that insurance. Have him diagnose it properly and be prepared to replace the engine.
Either way, new short blocks are still available last I looked for around $3500-4000, then rebuild your head for $1000, then add a few thousand for labor and other repairs, so plan on ballpark $10,000 no matter which way you go. Cheapest route might be if you find a good running engine to drop in but then unless the head gasket (and valve stem seals) has been done at some point in it's life then you may be back to the same spot in a couple of years.
