Since you've got the 2.8 in there, why not upgrade to a 3.4? Almost bolt in. Use the same accessories, intake, wiring fuel system as your 2.8 does. If you really wanted to get adventurous, you could try to leave the camaro intake on and all that and rewire and upgrade the fuel system.

I'd say go with the 3.4 if you're gonna put another engine in. Best bang for buck I think. You get the extra horse power with the ease of "drop in" (minus a few things, ie starter). 2.8 you've still got a pretty gutless engine. With the 4.3 or any other, you're looking at a full on drivetrain swap.
