My newly rebuilt '61 261 has a hot-idle oil pressure of greater than 30 psig (off scale of the '48's old gauge).

I changed the oil after breaking in the cam. (I was bored and wanted to crawl around under it.) I used a new, clean bucket and let any metal settle out. I didn't see any metal in the oil but it showed one tiny speck of metal on the oil filter. I'll be doing a 125 mile oil change tomorrow.
