More torque than nissan-zytek VK45 for sure; but "boost boosted" HPD 2.8 and the larger 3.5 V6 (basically the same engine that arx05 will use next season) ligiers were in the same torque range.
Nissan LMP2 V8 was in the range of 540Nm and 500-520hp @7000rpm.
Pre 2014 Grand Am 5L V8 were almost spec engines with torque and power figures more or less equalized by bop. Something like 580-600Nm and 500-520hp somewhere between 7000 and 7500rpm.
According to my most recent sources:
Corvette DP 5.5L in 2014 had about 560hp@about 7000rpm with 640Nm torque range. Power was nerfed in next 2 seasons to about 540hp in 2016.
Ford V6 3.5L was in the range of 550hp @ about 7300rpm (it could rev up to almost 8000rpm) but had less torque than corvette DP, 600-620Nm torque range.
Even if because of bop restrictors size decrease, very likely cadillac dpi can't reach 600hp, I can't expect nothing less than 700Nm from that 6.2L.
A torque amount unachievable for any other kind of engine, most of Nm already available at lowest rpm.
Repeat, to me max displacement for NA should be to set to 5.5L, but is just my opinion.
