i am told you need to do quite a bit of wiring to drop a 4.3 in the efi 2.8 models. as well as the trans. but yours being a 85 model i dont think the 4.3 ever came with a carb set up. so i would just throw in another 2.8

Agree 100% And you can get camaro 2.8L easier ..and its a Drop in , 4.3L install is a pain an cost more, 350 is just point less unless your racing it, for something a daily etc 2.8L FTW !! End Of Story!
