Having put Vortec 350 motors in several vehicles, here are some tips:
1. The stock Vortec engines were supplied in 96 thru 99 Chevy trucks, etc and some 2000 vehicles like the Escalade. ALL require 4 oxygen sensors (pre cat and post cat) in stock configuration. UGH.
2. Companies like Fuel Injection Specialties in San Antonio can reprogram the computer to axe some of the stuff and change the gear ratio.
3. Only the 96 and 97 computers have no PassKey ingnition interlock.. use those years if possible
4. Engine doesnt rev very high in stock trim
5. Fuel lines need adapter to hook up. Use a chevy in tank pump

Injector setup is kinda tall for a Camaro hood, you might check before buying.

If you are going to take the fuel injection off, there is no reason to use a Vortec motor.....just use the Vortec heads
