hell you can even run the ecotec of the ld9 pcm/wiring...
what bugs me is that unless you swap ecotec/3400 none of your gauges will work...
that's why I have all autometer in my car... (you probably can swap a 3500/3900 but you'll have to use a 3400 harness/pcm) but you'll have to lose the variable cam of the 3900
if you want to go 3800... good luck, it's a torque monster and you'll have to redo/reinforce the stock frame and subframe of the car... It pulled my upper rad support like 1 inch even if I had urethane lower mounts....
