when did Chevy vortec come out
1996
The name first appeared in 1988 on a 4.3 L 1996 in full size trucks.
First of all Chevy did not make a vortec engine in 1987 or 1995, those engines are TBI / Throttle body injection engines. And yes they will interchange with no problems.
1996
what year did chevy come out with the vortex v6
The word 'vortec' is the name of the cylinder heads used in Vortec Model engines in the year 96'+ The engines that use the Vortec cylinder heads are the 4.3L Vortec, 5.0L Vortec, 5.7L Vortec, and 8.1L Vortec. They were only put on Gen I small blocks. If they are any other size Chevy engines and still retain the Vortec name then it's purely a marketing name, the same goes is it is later than a Gen I engine. For example the new 4.2L I6 from GM retains the name Vortec, but it does not actually use Vortec heads as these heads were only made for OHV engines, and the I6 is an OHC engine. The Vortec heads are based on the LT1 and LT4 head after they were discontinued along with their reverse flow cooling design. It is simply an effect made in the head similar to a vortex to better atomize the fuel and air intake charge when entering the combustion chamber, it is not a different type of motor.
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

chevy didn't come ouy with vortec heads until the 90's . I'm thinking about 96, so just because they are centerbolt head doesn't mean they are vortec. sorry pal
pre-1988 Chevy 350 5.7 (in trucks) were carbed (with the exception of diesels) so that is the first thing to look for. after 1996 the 350 engines are vortec- until 1999, when they went to a 327 5.3 litre engine. (with the excption of the W/T) but still vortec's. and of course, the plastic throttle body cover that says...Vortec
