Engine JUST gave out!?! I NEED Swap Suggestions...

I have been away from this forum for a long time (while in Iraq, and various other places WITHOUT my car ...) but I'm back with a BIG issue. I need some help, and suggestions. I have a '98 GT with just over 90,000 forced induction miles, and tonight my non-PI stock motor is no longer with us. I want to do a complete engine swap ( 5.0, 4.6PI, 5.4, cobra) and possibly still use a good portion of my accessories ( 6 month old custom FMIC, Vortech S/C, $1,400 worth of tuning software/hardware). Im looking for suggestions on what I should do. Please help me out! Just to let you know, I'm a Marine and I'm married so I'm clearly on a budget, lol! I'm looking to keep it fairly cheap, but I want the car to perform! I drive it hard and want to try to keep it forced induction. A relatively simple swap is ideal as well. I am very knowledgeable, but I dont want to really do any fabrication, or rewiring. What options do I have? And for a little sympathy, I JUST got this car back ONE week ago from getting new a new wing, hood, and paint! I did an oil change, radiator flush, tune up, cleaned my air filter, and gave it a good wash/wax, and minutes later said goodbye to my engine! Bad night for me altogether, so ANY help will be GREATLY APPRECIATED! THANKS IN ADVANCE

Yes or no to a 2000 S281 Saleen engine (complete with ECU and harness) with 88,000 miles for $900? Does it have forged internals? More HP? All of my stuff would mate to it, correct?

I like the idea of the 4V from the Mark VIII. I would need the harness for that engine as well, correct? As far as rebuilding my block, I dont think it is in good enough shape. There was a lot of metal circulating thru it during the end of its life. Also for that reason, I think I'm going to stay away from the shortblock. It would be a great option, but I would have to invest too much money in addition to it, that I think I would be better off with a complete engine. Thanks for the help so far! Is there anything else? Anybody else? What about the Saleen engine?
