How does a vortec engine work?

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.

Will a 1999 vortec intake bolt to a 1996 throttle body injected 350 block?

NO it will not. You would need the heads off the vortec engine to make it all work. The 96 that you are talking about should be a VORTEC engine already from the factory. But you may have an early 96 and that is why it is a TBI engine. That was the year they switch to a vortec. 96 TBI no such animal,TBI OBD2 no

Can a 305 intake out of a Chevy custom deluxe fit a vortec engine?

Probably. But you may need to enlarge the 4 center bolt holes, as the angle is a little different. NEW ANSWER: That is TRUE when you install a TBI / Throttle body injection intake on an early modal carbureted engine / set of heads. You can't drill the intake bolt holes out to make it fit on a vortec engine / HEADS. Reason being is because the bolt holes in the vortec heads and intake are straight up and down.
