The tranny as well. The EcoTech and GM v-6's have a different bellhousing pattern. The cheapest method would be to find a running donor 3400 Grand Am '00 or newer and pull the motor, tranny, engine bay harness, motor mounts, rad etc. Look for a wrote off vehicle that runs. Then exhaust mods as T_S_T said. Keep all PCM sensors on the 3400. There is no way to estimate this until you find a donor car, but if it is in good shape it should have everything you need..
