You're welcome. Nothing noted on the receipt I got from Bowtie. I couldn't pull up the site either. It is a stout piece, I'm confident it will hold up to my 400 hp setup. If you are talking 600+ hp I think it would hold if you had solid motor mounts. I'm assuming you'd have a 4-link rear setup or something similar. It is a hefty gauge tube and the ends are solidly welded all the way around the mounting tabs. I feel like I'd lose a motor mount before this crossmember gave me any issues. Maybe in a few years I can report back on how it holds up to boost...
As far as compatibility, there are a few different mounting holes that allow for some adjustment. Mine installed just fine. Of course after cramming an old LT4 and a T56 in my '87 S10, everything about this car feels easy.
