It looks like the one from Jacob's to me:

It's described as both thicker and wider, no direct mention of length. There are videos on this that I did not watch, I think it includes one on why he feels his belts are better. It seems to me that it may necessitate a different high speed alignment due to the dimensional differences because the belt may be riding in a different spot in the pulleys. And I would guess that it may not provide the full speed range.(?)

I looked at one of the free videos Jacob Anderson offers about belts. In it, he shows the belt he uses and sells, and the markings read 15 x 675. He says it is .6" wide. 15mm converts to .59" and 675mm converts to 26.57"

That is close to SS OEM dimensions. A bit wider and a smidge longer.

That 'should" result in a small shift in range.

I would perform the high speed adjustment with the motor belt at or very slightly inside the motor pulley periphery.

Belt wear will move the belt into the pulley(both). That wear will move towards the oem dimensions(new).
