I did my 3.4 swap about a month ago and was browsing the salvage yard. I found all of this stuff for $300.
3.4 core engine with supercharger (engine not in picture)
Some rear springs, don't know how much lift.
Cracked fender flares

Got the supercharger installed and it runs great, the bypass valve actuator hits my heater control valve. I don't think this is a problem with the newer black S/C but for the price I paid I'm not complaining
