My '76 has had extensive motor work with the P.O., including porting, high  
compression (9.5 to 1), cam, lightened flywheel, and headers.  It runs  
beautifully, now that the carbs are rebuilt and tuned.  I  run 20W50 
conventional oil 
in it.
 
My question is that my oil pressure gauge shows only about 35 psi hot under  
load, and maybe 25 psi hot at idle.  That seems low to me, but I don't have  
any basis for comparison.  Also, I'm not completely positive what oil is in  
the car, as the mechanic who changed the oil last time may have put in  10W30.
 
What is the usual oil pressure hot under load and at idle for these  cars?  
Could my gauge be reading low?
 
Thanks as always.  Have a great holiday weekend.
