Other than a time constraint that's too short to do a proper swap, do you have a budget constraint as well? Is this something you have $5k for at this moment? I'm not even sure you could get a stroker motor shipped to you in that time frame anyhow.
If I was you, you'd be fairly handy with the tools and willing to dig in on some interesting territory. So this is what you'd do if I were you. You'd get a running 4.0 from a salvage yard or a local shop, used but not rebuilt, and put it in the machine because you only have a week and a half right now. Then you'd take the motor you blew and scrap it. Next you could either save your $ toward a Stroker that is built already, or you could buy another solid block, order some pistons, crank, head, etc., get a machine shop to square it away and then start building your own stroker motor.
