Before you go buying that none vented opti your may want to go doing some more research on the engine swap, It might be easier to throw a cam in and convert it to a vented opti and reuse your intake and such.

On the intake alone: Fuel lines on the F-bodies are different on the 92-93, then the 94+s. I'd assume the same is true for the vette motor. the 92-93s are 22lb injectors, 94+ are 24s so you need to swap injectors. Vacuum lines/Evac are different. Throttle body linkage MAY be different ( it is for autos ) The EGR connections are different, your going to need blockoff plates, and if you don't already you'll probably need to program the EGR out?

92 Vette may ( sorry I'm not sure ) had oil coolers, if you car doesn't then you need to remove it and buy an adaprter for the oil filter.

Also the oil sending unit is located on the side of the engine, you'll need to swap over your original S.U and plug the hole on the side.

this more then anything could be the big issue:

The none vented Opti is different then the vented in how it's wired, you are going to need a different pingtail for the conenctions into the wiring harness. I don't even know if it will work? I don't know of anyone that went from vented to none-vented.

Thanks all I can think of off the top of my head.
