Silver oil Ok...i just put a 97 motor in my 93, with ported heads and 503 yada yada. The motor has 52k on the clock. Been sitting for 6 yrs. So i put it in, got 100-200 miles on it since. Went to the track and made 8 runs in 6hrs, high 12, low 13's. So today i check the oil to kinda see the state of the bottom end. Oil has a good silver twinge to it. I have always thought that this is a sign of bearing wear, correct? Or is this something to be concerned with? Or dont worry about it till u see copper? What are your guys thoughts. Thanks

Monitor the oil pressure and keep an ear out for knocking and hope for the best.
I would drain it and cut open the filter before I even turned it over again. Inspect the drain oil especially the first bit that comes out as metal will likely settle low in the pan.
Hopefully it is just a little crude from a dry start and inspection turns up nothing else suspicious.

I hoped it was just the hard racing. Oil pressure is still holding 60 on cold start and about 50 on highway and 40 on hot idle. So i will change oil and cut open filter. What would u expect to find in a motor that was on it's out?
Your pressure seems reasonable except for 40 on hot idle which is very high IMO. I have 20-22 on mine with 5W30 oil.
What weight oil are you running?

silver is worth quite a bit...pawn it?
Best of luck man.
Im guessing the RP 20/50 came from it being the only **** on the shelf besides 30weight lol. Thats why I used Vr-1 to throw in mine befor racing, 5/30 was actually in stock. I just do the 1 quart mixed with mobil clean 5000.
sitting for 6 years, it could just be moisture getting mixed in with the oil.
