Nope, different heads
No, but if the 96 has the 5.7 Vortec engine then it will have different heads which give it more power. ETA Question: Can I put the '96 vortec heads and intake on the '93 engine? You will need a vortec specific manifold. Edelbrock makes one
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,
If you are referring to the intake manifold , it has a lower section and an upper section , the one piece intake manifold wasn't used until the 2001 4.0 L SOHC , and if you are referring to intake valves - one intake valve per engine cylinder on the 4.0 L SOHC engine
There will be 3 core plugs on a 4.3L V6 Vortec engine: 1 each side of the block and one at the back, in the bellhousing area.
Number one is the front cylinder on the driver side.
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.
yes ,I have change one out with a old 350 it had lot more power . I used the old heads to with vortec intake you have to slot the four bolt holes .but it will work.
Drivers side front
The intake stroke, number one in a 4 cycle engine.
Most major auto part stores will stock the standard EGR valve for a Vortec 4.3-liter engine. You may have to visit several to find one that has it.
A 2000 Silverado 5.3 Vortec that is hard to start and misses on one side of the engine might have a problem with the coil pack or the spark plugs. It could also mean that the block is cracked if the engine is prone to overheating.
Vortex engine? Got me. I thought Vortex was just a brand of supercharger. I believe you mean Vortec engine.. GM also called this the L31 (they use 3 letter/number codes for everything) This system used a SCPI (Sequential Central Port Injection) system... and the fuel pressure regulator is on the central unit, which is INSIDE the intake manifold- you have to remove the upper intake manifold to get at it (plastic part), and the Fuel pressure regulator will be on one side of the central unit where all the fuel lines go to, it has a tube on it open to the intake manifold (to read intake vacuum)
