Just wondering if a water pump from a 350 chevy engine is the same size as the one on the 4.3 Vortech???????

Thanks a bunch

The reason is because i had just bought a new pump for my truck but didnt need it but now my 92 blazer water pump went out

so i was going to use it on the blazer but didnt know if it would fit or not.

Sorry, I didn't explain myself good enough. Any 87-95 sbc or 90 degree v6 (4.3L) will interchange. The pump has to be 87 and up because it has to work with the serpentine belt system, which changed the direction the pumps spin (reverse flow). Another difference with these pumps is the coolant bypass hose for the heater. If you have it(probably not) you use it, if not you have to cap it. Other than that it will work. The 96 and up are the same pumps for the 4.3,5.0,5.7(not LT1) vortecs.
