I'm thinking that pulling the motor is the only option....so the car is down for a little bit....but in the long run it is the best option...once again the motor might have been toast when I got it...who knows how it was driven-maintained by the PO's...& I know for a fact that the guy that built it seriously overheated it at least a few times (he said 230F water temp) so that might contribute as well.....
Once the motor is out it will be easy to inspect it and determine the extent of the damage and most cost effective way to get it running properly again.....

Sorry to hear this Brian. The good news is that you've caught it early enough that this is almost routine maintenance. This'll just be your yearly rod bearing replacement. Blowing up a motor would have been a way bigger bummer.
Once the motor is out, it's pretty easy to install the new rod bearings & scraper kit. Let me know if you have any questions. I've been down this road . . .

Bearings should be relatively cheap, it's all the other stuff that you might as well do since you're in there anyway that really starts to add up.......
I hear these things pull really good with a pair of turbos

I do hope I caught it early enough that the scrapings didn't get everywhere and essentially ruin the engine...
I've already got my "list" of parts to buy
1: Rod Bearings
2: Scraper-windage kit & spacer
3: setrab oil cooler (20 row already have)
4: accusump...or drysump (debating this one)

I really hope its "not that bad" a clean up.....& since I do not plan on re-using the factory oil cooler in the radiator that makes the clean up a bit easier too

UPDATE
I just got back from the race shop and saw the cut open oil filter and oil.......there IS small bits of gold colored metal in it....but really not much....the oil is fairly dark indicating it got pretty hot, but does not smell burnt.....
So what do I do now...... my only options are to pull the motor and inspect-replace the rod bearings and install the oil cooler + accusump & scraper-windage......of just install the cooler-accusump and run this engine until it fails.....but I don't like the idea of getting lots of little metal bits in my new accusump and setrab oil cooler....

You do need more options:
Drill crank, or not
AND either
Windage system and/or accusump
OR
Dry sump
OR
No oil control changes
AND
Spacer or not
Now I went for the windage system alone. This is because I didn't have the scratch or time for a drilled crank. My car is streeted and I can't see how to mount the tank for a dry sump. Instead of a better ($$$) approach I'm checking the oil filter and getting the oil tested periodically. I don't have data on this as I've switched to tracking my 944 for a few reasons unrelated to oiling problems.

Brendan, it's some metal .... like any other V8. It is a problem, and it can be solved ... no voodoo. I agree with you. RKD I think has a good point. All the rest are bandaids. Target the problem and solve it. If the issue is not enough oil to 2/6, give them more oil dammit And if the issue is aeration, make it harder for oil to be winded. Deeper pan, slanted somewhere else, drysump, no more aeration, no more windage.

There are actually oil filter openers. I puncture and snip to get the guts out
OK, ok, okay...
Your best option is a drilled crank and a dry sump system. If you're not up for that then it's time to compromise.
BTW - The "scaper" is a very complex system of baffles and channels. There's a scraper in there. There's also a cool sump cover with trap doors.
