Yes they will fit right on there with no machine work are problems.
The 2001 model of the Light-Duty Silverado 1500, had an option of four engine sizes; a 6.0L Vortec V8 engine, a 4.3L Vortec V6, a 4.8L Vortec V8 or a 5.3L Vortec V8. The Heavy-Duty 1500HD comes with three engine options, these are 6.0L Vortec V8, 8.1L Vortec V8 and a 6.6L Duramax V8
will a 4.3l vortec starter fit a 305 vortec?
The 4.3 Vortec engine never had a carburetor.
" vortec " is a title that GM uses on some of their engines
The vortec has bigger pistons
Look at the intake manifold. A vortec engine has 8ea. All the others have 12ea.
No it is not even close.
No because the ports on a tbi head are different than the ports on a vortec head, vortec heads need a vortec intake however you can switch a carburated engine to a tbi engine because the heads are the same
NO. That would be the TBI / throttle body injection engine Not a vortec. The vortec will not work in the 91.
A vortec 5.7 is a lt1 based engine.
There are 4 different Vortec engines for that year. Stock horsepower at the crank are: The 4.3L (262ci) Vortec V6 has 190hp The 5.0L (305ci) Vortec V8 has 230hp The 5.7L (350ci) Vortec V8 has 255hp The 7.4L (454ci) Vortec V8 has 290hp
Not without extensive (and expensive) modification
