I ran into this with a '97 Yukon (same vehicle) and after months of running into this problem intermittently, it turned out to be a small harness in the distributor housing that had corroded ... discovered this after already replacing the obvious ... cap / rotor / coil / and ignition module.
The vortec has bigger pistons
Look at the intake manifold. A vortec engine has 8ea. All the others have 12ea.
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
The 4.3 Vortec engine never had a carburetor.
" vortec " is a title that GM uses on some of their engines
A vortec 5.7 is a lt1 based engine.
will a 4.3l vortec starter fit a 305 vortec?
No it is not even close.
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.
Yes as long they were mounted on the same side of the engine.
