when did Chevy vortec come out
1996
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
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.
There is no difference what so ever. Same engines.
No, but if the 96 has the 5.7 Vortec engine then it will have different heads which give it more power. ETA Question: Can I put the '96 vortec heads and intake on the '93 engine? You will need a vortec specific manifold. Edelbrock makes one
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
what the difference in the engine for a 2005 chevy Malibu without electric power steering to one with electric power steering
In 89, Chevy introduced the 1st generation vortec head. It has a different angle, thus using a different intake manifold, and self adjusting rocker arm.

The name first appeared in 1988 on a 4.3 L 1996 in full size trucks.
