Semi-Hypothetical: What's the cheapest/fastest you could change rod bearings?

Disclaimer: I know this is "wrong". I don't care, please just answer the question.

The SVX spun a bearing. It's been getting there for a while, but it's gone now. Hideous knock on start until it's got oil pressure, and mild knock at all times. I was planning on rebuilding the engine next winter, but this has forced my hand a bit. The big problem is that I'm at school, 1000 miles from home. I have to get the car back, or scrap it here (not happening).

My options:

-u-Haul 10' truck and car hauler: ~$1,700 (We were going to rent a van anyway to get stuff back)
-Have a number of quotes sent to shipping companies. Last time I checked it would be around $1500.
-Rebuild the motor.

Now, the question I asked: Lets say you pulled the engine, stripped it down, pulled the wrist pins, split the block without actually removing the pistons, popped the rods, had the crank polished, and re-assebled with new rod bearings. What would I need? I have all the internal o-rings remaining in my gasket set, everything else is new from this past summer (~1500 miles on a head gasket job). New head gaskets, obviously, but other than that?

I know very well that's not the correct way to rebuild an engine, but could it be done to make a 1000 mile trip?

It is impossible to split the block without removing the pistons. It may be possible to remove the cap off the rod to replace the bearing...but I don't recommend trying it. You'd be better off buying a shortblock and swapping it.

You are not going to be able to change the bearing w/o removing the crank and having it machined and end up using an oversized bearing and a new rod. If you can swing it... Find a junkyard motor, rent an engine crane and knock it out where you are if you can.

Re: Semi-Hypothetical: What's the cheapest/fastest you could change rod bearings?

Okay, thanks guys.

Equipment and tools aren't an issue, I work at a garage here. Part sourcing is though, there are no SVXii in town and zero chance of finding an EG33 lying around. If I was able to that would be my choice, but it's just not doable.

Cam, fully hypothetically now, if you removed the wrist pins first, why wouldn't you be able to split the block? The rods will just fall out of the pistons. My thought was to avoid unseating the rings.
