I'd say it all depends on your money situation. Get to know your local J/Y people. They can be your best friends. If you can pick up a nice low mileage engine and have it redone, "if nessasary" that's the route I would take. As long as your engine is running now, why spend a ton of money on a block. If you just have a bunch on money you want to get rid of then, send it to me.....LOL
