First, follow dirtyd0g's advice. Get in touch with XR7 Dave. He frequents SCCoA. Send all of your good parts, if not the whole engine to him. Me, I'd send everything (manifolds, cam sensor, etc.) so you can get a whole engine back that just needs unboxing before you plop it in the engine bay. None of this short block or long block install prep.
I went through this with my son's SC, TWICE! By the time I was done, it cost me more for a stock rebuild than what I could have paid Dave for a better performing and more durable engine. If the engine is done right once, you shouldn't have further problems.
Second, replace all of that EGR stuff in the back of the engine while the engine's out. Or get a tune to eliminate it. My EGR components were allergic to engine swaps. Worked fine before the swap and failed after the install... ...TWICE!
Third, if you do get a new engine, get a tune to turn on both fans earlier to aviod any cooling problems. Or at least wire up a couple of temperature switches to switch them on early.
I wouldn't mind short block or long block swaps with the Windsor or Mod motors but when it comes to working on an SC, give me a complete engine any day.
