I have an 84 RC that I recently swapped in a freshly rebuilt 360 (now about 400mi on it) in place of the original 318. I am going to install an oil pressure gauge here in the next few days. It’s basically stock, aftermarket intake and camshaft. What is the normal operating PSI range idle to cruise (fully warmed) and where does the danger zone begin?
Thanks,

I prefer at least 30 psi at idle and about 40-50 at highway speed. Anymore then 80 psi is too much.

On a stock gauge where would 30 psi be and where would 40-50 be?

That stock gauge your refering to, is it that one with only hash marks from ( L l l l l l H )? If so you will have to take a manual gauge and "T" off of the oil pressure sender on the block behind under the distributor. Then you can get a compairitve reading. However I have not seen any two stock gauges that are alike, or calibrated. I wouldn't rely on the stock gauge period, it is not much better than an oil light! I would take an attach a manual gauge and rely on that from here on out. If you only want the manual gauge for calibrating the stock gauge, thats fine, take an replace the electric oil psi sender first and check the nuts on the back of the oil psi gauge in the instrument panel and be sure that the bulkhead wiring plug has not been contaminated with water and corroded the plugs contacts. This will remove potiential problems in the future for your oil psi gauge and allow you a more accurate calibration with the manual gauge.

Man that Mechanical guage should have been in before the motor was in, but get it in now, use auto-meter also

After you get the mechanical guage in, just remember the ol' rule of thumb: at least 10psi for every 1000rpm. In other words, 1000rpm should see at least 10psi, 2000rpm should see at least 20psi, 3000rpm/30psi, etc.
