I'm helping part-out a beloved vehicle and passion project of a family friend who sadly unexpectedly passed away. I know most of the history and assisted with building the car, so I can answer most questions beyond what is described below. Still working on locating the paperwork, receipts, etc. as of the date of this listing on 7/23/2025, but they are definitely still around.
This listing is for the Engine, Transmission, engine wiring harness, and tuned PCM from the car.
Around $50k spent originally, asking price is negotiable, all reasonable offers will be considered, serious inquiries only please.
1000-ish miles of street driving since completion in 2021(looking for records to confirm exact number), never saw track use of any kind. Primarily was driven to and from car shows during the summer months.

Info from memory(looking for paperwork to back it up, will update when I can):
Hutter gave the thumbs up for 2000+HP if so desired(it wasn't)
Injector Dynamics 1700 injectors (190lb/hr @58PSI)
Engine made ~650HP naturally aspirated
The car it was removed from made 950HP at the wheels with a custom Procharger F1R setup in a 1998 F-Body and had potential to make more with bigger fuel pumps than what were in the car.
Rossler Terminator 3 4L80E transmission.
Circle D converter
Kooks Long tubes
6243 PCM with flex fuel(E85) capability and 3bar OS, calibration professionally modified to correctly operate a 1998 F-body fuel gauge. All engine tuning was performed by Hutter Performance.
Engine/trans harness is set up for a flex fuel sensor on the drivers side strut tower of a 4th Gen F-body, and the under-dash connectors are pinned for 1998 F-body(this is slightly different than 99-02). Engine harness has been professionally modified to allow the factory tachometer to operate correctly with the 6243 PCM. This will plug directly into a 1998 F-body and operate like OE. Dash harness connectors can be re-pinned and the calibration can be modified to work like OE in a 99-02 F-body if desired(willing to negotiate that service into a deal).
Engine/trans/harness/pcm are still attached to each other and also to the cradle from the 98 F-body it was professionally removed from.
The complete Procharger F1R setup for a 4th Gen F-body as well as the custom built radiator to clear the large air filter on the procharger are available as of 7/23/2025 and can be worked into a package deal as well.
