IIRC They upgraded the pump in 97 to a high volume pump because of the oil squirters in the 506 engines, that weren't in older 6.5s. 96 was a change over year. some trucks got 506 blocks, some got older version without high volume pump & squirters. You could try changing out the pump to the proper year for your engine (99). Hope it helps. Also normal pressure for oil squirter blocks runs lower than earlier blocks. Normal pressure when warm, is around 20 at idle, 40-50 at cruise RPM.
I hope you fully primed the lube system before starting up the new engine. If not, your cam bearings are most likely toast.
