Motors Manual 20th edition gives the range for 48-50 models as between 3 1/2 - 5 1/2 psi. Service Counselor issue Vol 22 #1 gives the factory spec for the 48 Custom 8 engine as 4 - 4 3/4 psi with a delivery of 1 pint in 45 seconds. What I have never seen mentioned with that 1 pint delivery spec is the speed the engine is supposed to be turning when measuring. Since the 22 - 23 series were for all practical purposes except trim placement identical, the 48 factory spec should be valid for your 49.
