Maybe there IS a reason why Ford is shy about it in the shape of the 5.2 Voodoo engine in the GT350, which is rated by Ford at 526hp & 429lbft but puts down 470hp & 375lbft at the rear wheels.
Might not be good for the Voodoo if the Aluminator XS makes nearly the same HP but has more torque, especially below 3500rpm where the Voodoo is relatively weak (Voodoo is down by 30lbft at 2600rpm).

This.

A decent normally aspirated engine these days makes about 75 ft*lbs of torque per liter of displacement.

It takes an exceptional one to make over 80 ft*lb/Liter.
