Yes. The L05 (350) engine in the B-body used a hyd. roller cam, as did the L03 (305).
The same code engines used in GM trucks did not come from the factory with the roller cam. Although the block has the provisions to upgrade to the roller assembly, it only came with a hyd. flat tappet cam. If you were to change one over, don't forget the pushrods (they are shorter with the roller setup).

It don't have a roller cam That's for sure.
Hydraulic lifters would be STOCK from the factory. On the 84 engine.
Its the variator on the intake camshaft that is making the noise put engine flush into to the engine run it for ten minutes and then change the oil and the noise will be gone.
The 1995 Ford Crown Victoria uses the 4.6 liter Single Over Head Cam engine from the factory . It has ( 1 ) camshaft on the top of each cylinder head

No it is not. It is a factory TBI / Throttle body injection, None roller camshaft 5.7L 350 engine.
With proper maintenance, the camshaft should last the life of the engine.
The camshaft operates the valves on a 4 cycle engine.
Typically the OEM engine oil viscosity. Nissan's Hydraulic lifters for the SR20DE and SR20DET are usually recommended to be placed in 'engine oil' when the engine is undergoing rebuild, which in this case would be 7.5W30 (from factory) or approximately 10W40 depending on the viscosity you can find at your local store.
A two-stroke engine does not have a cam or camshaft. Seeing there is no intake/exhaust valves it would be pointless to have a camshaft.
There is no camshaft in a 2-cycle engine.
