No they will not.
There is a great write up with step by step instructions here for the 4.3 5.0 5.7 vortec Engines. Also lots of tips in thread.4.3 5.0 5.7 Vortec Intake gasket replacement guide pictures directions and picsSee link below
No it will not. The 96 vortec has a crankshaft sensor and alot of other sensors on the engine that is required so the transmission will work that will not interchange with the 92 engine. Even the fuel pump would have to be changed. You must put a VORTEC engine back in the 96 so everything will work correctly.
If you are sure that it did not freeze and crack the block, Then the intake manifold gasket is leaking. That is a common problem with the vortec Chevy engines. You need to replace the gasket with a factory Chevy gasket from the dealer.
to replace the intake gasket would be about 4 hours labor. parts would run about $50
The knock sensors yes there are two are located on either side of the motor (4.3LTR Vortec) below the heads in the center area of the engine block. There are a place for another sensor just above where the knock sensor goes but these are for other sensors.

Yes. White smoke is an indication of a coolant leak which could be caused by an intake gasket
There are a total of 4 O2 sensors 1 on the left AND right exhaust manifold 1 before the catalytic converter and 1 after it.

Cap, rotor, wires and plugs, and if they've never been changed, probably the Oxygen sensors as well. Check the EGR valve, make sure it's opening properly and hasn't caked over with deposits. Get a new gasket before you remove the EGR valve. A PCV valve would probably be a good idea. Of course, make sure all of the filters are in okay.
Because a true 350 vortec I think relies on the vortec intake in order for the pressure to stay correct. I just remember i had my vortec box off of my truck one time I started it and It died just put the old vortec air intake back on and it should be fine. sounds like you have vacumn leaks around the intake manifold, this can be checked with a can of carb spray,
Heater return pipe or hose, leaking intake manafold gasket.
The water level drops, and you have to add to it every so often. If not, it will get hot, often, and easily.
No it will not. Those 2 engines have a total different type of fuel system and sensors.

well, the 93 has a spider injection unit in the intake manifold. ten bolts and a gasket...
Yes you can. There are a few sensors that are different but after swapping them over it will run. The mounts and bolt pattern are the same. You will certainly be stepping back as far as performance and power goes. Not only does it obviously have fewer cubic inches but the heads lack the flow that the 350 vortec heads have, The 305 Vortec heads also do not have the famous Vortec heart shaped combustion chamber as the 350 heads. The 305 head also has smaller valves and smaller runners. You can also swap the other way and place a 350 vortec in where a 305 was. I have personally done these swaps with no troubles at all.
should be the same mounts as they are both small blocks.
Type your answer here... I had the same problem with my 96 Tahoe.. Vortec 350. Problem was a blown intake gasket.
Yes an 89 350 will bolt up to original Vortec heads. However, Vortec heads have an 8 bolt inatke manifold that is different from the standard 89' intake. Its worth mentioning that the intake manifolds changed in 1986. Prior to 1986 all intake manifolds for a sbc had 12 bolts. These 12 bolts all secured the intake to the head at the same angle. In 1986, or primarily in 1987 the intakes 4 center bolts were changed to a steeper angle. With the introduction of the vortec head came a new 8 bolt intake eliminating the 4 center bolts. If you plan to use Vortec heads on any V8 be it a 305,327,350 or bigger, you will need a Vortec intake manifold as well. You can also buy an after market intake to run a carburetor on a set of Vortec heads in place of the TBI injection.
Short Answer: it is not supposed to change. The actual timing is determined by the ECM using input from several sensors including the CKP and the CMP.
That is a common problem with the Vortec engines, First place the gasket is not made of much as you can see. Antifreeze eats the gasket up over time. The ORANGE antifreeze is BAD. If the Intake was OVER TORQUED that will cause it to leak/ Go bad too.
The Vortec Motor hasn't changed sence it came out. it will fit perfectly.
