no, they are the same age
no the vortec is faster
Yes it is, as long as the 350 pump is not a late model pump.
Yes it's the same pump
57 - 61 psi for the 95 jimmy 4.3 vortec so it is probable the same
No it is not even close.
the water pump is turned by the timing belt and it is recommended that you change the belt at the same time as the water pump
You do not need to replace a water pump and thermostat at the same time. These parts do not ruin each other.
The water pump and cam are driven by the same belt. The oil pump has no relation to these.
Yes they are the same.
no its quite the same
Yes
