I would like to know if my 2002 chevy blazer with a stock 4.3 vortec pull 2000 lbs ?
The 1996-1998 vortec 350 was an updated version of the older vortec style fuel system used on the smaller v6 engines. All eight injectors are mounted inside the intake manifold. You have to split the intake manifold and remove the upper portion. Once inside you can remove the Central Sequential Fuel Injection (CSFI) unit as well as all of the attached tubes and poppet valves. CAUTION - Pay attention to the location of each injector and the location of it's corresponding tube and poppet because they must be placed in a sequential order hence the name. The injectors are popped out the bottom and then reassemble in reverse order. Hope this helps!!
under the plastic cover that says vortec there is a huge aluminum cover called a planum disconnect the hoses to that remove the throttle cable unscrew 5 bolts i think it is remove the planum under that is what u be looking for

The 96'-98' vortec 350 has 8 fuel injectors that are contained inside the intake manifold. the vortec uses whats called csfi which is called central sequential fuel injection it has 8 electronic fuel injectors and 8 mechanical ones thesa are the ones that deliver the fuel.
The Vortec Engines with the Spyder, or octopus type fuel injectors had issues with the clip on the fuel injector harness breaking. thus, causing it to come loose which would cause random misfires. also causes could be low compression, bad plugs and wires, dirty injectors, cattilytic converters.
