I have a 1990 toronado trofeo and I am dropping in a supercharged 3800 series 2 (motor and tranny) from a 1997 Grand Prix GTP. Any help would be greatly appreciated. Thanks. I hace the engine wiring harness and PCM. I was told that I needed h-body mounts and it would fit.

Also... you might want to look up "Frankenbonne" here. That was a swap into a 90 b'ville.
