if you are talking about the popular heads everyone wants. it started in 1996.
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
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
It is a V6.
The 4.9 vortec means that it is a 4.9 liter v8 probably.
There were a lot of different versions.
V8 6.0 liter Vortec
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
A 1995 Chevrolet Tahoe has a 5.7L 350 TBI V8 for a engine, not a vortec.
5.7L
The Vortec 5.3 Liter V8 engine produces 295 horse power.
The 4l60e from the 4.3 vortec will fit the v8 motor, 3.1 and 3.8 are different.
5.7L Vortec 5700, of course!
