Actually Chevy did make a vortec before 96 I know for a fact that some '94 blazers had a 4.3 vortec that put out 200 hp. Not sure about full size, but the s10's did have a vortec. Just correcting ya :)
Sorry, but I think the vortec motor was first introduced in 1989.
Chevy has had the 4.3 liter V6 since 1985 or 1986 and even the carburated version was called Vortec.
I have a 1993 Chevy c1500 v6 4.3L and it too is a Vortec... three years later they came out with a Vortec generation 2... if your V.I.N has a letter Z for the 8th digit then it is a Vortec (1995 and earlier models)
I own a 1994 k1500 Chevy Silverado. It is throttle body fuel-injected and with a 5.7 V8 puts out over 200 horse power. My friend on the other hand has a 1996 GMC Sierra with a 5.7 V8, which is a vortex motor, and my Silverado puts out more horses because I have dual straights, so I don't think the vortec\x has added a lot of power to the truck.
I love my 1994 chevy silverado 4.3. it's 15 years old pushing 300,000 and runs like new. I live in the hills of TN and drive 130 miles a day. I get just about 20.1 mpg. I have a flat cap that covers the bed so that helps with mpg. I hope me and old blue keep run for years to come.
All in all...good comments about the VORTEC 4.3 V6...Hope I am as lucky as the other commentators with the new Silverado 2009 WT 1500 LS I just bought. Thanks...Kentucky/Like a Rock!
I have a 1994 S10 Blazer. It has 190K, Vin = (W) = Vortec 4.3 200HP engine. The truck runs great, I did have to replace the spiders web looking injector at about 160K, other than that the truck runs great. Sport.
I have a 94 as well with the Vortec engine... over 270,000 miles on it and no problems... drives and performs well...
The 4.3 V6 Vortec came out in 1991. They started putting it in vehicles in 1988, but didn't call it the Vortec until 1991.
