Seller just called me back. He still has it, it's been sitting (inside his shop) for 15 years! (yikes)

Supposed to have come from a reputable dismantler...I may go take a look at least.

Any idea how hard it would be to fit this into some other M104 powered car without having the wiring harness, intake manifold, or ECU?

HFM M104s should have no problem. Use your own wiring harness, but it'll require your old valve cover.

ECU, use your old ECU should be fine, but to get any more HP, needs a tweak from Speedtuning in MD.

Use your old intake manifold as well.

Pre-HFM cars? I wouldn't do it. Way too much trouble.

Good info. Was it 1993 that the M104's got the HFM computers? Does the engine stamped numbers (like in your photos) give an indication of the year the engine was built?
