LS1 v8 5.7 (350)
310 @5,200 rpm horsepower
(325 w/ Ram Air)
340 ft-lbs @4,000 Ram Air
(350 with Ram Air @4,000 rpm)
Look at the torque specs. I got the numbers from this site and a pontiac dealer brochure....does the 91 L98 actually have more torque than the non-ram-air trans am with the LS1.

You're point being ... We know this. What the LS1 doesn't have down low, it makes up for on the mid-upper rpms. Likewise what the TPI doesn't have in the upper end, it more than satisfies on the lower-mid end. Also if you noticed, add the LT1 to this comparison and you'll see the torque has remained relatively the same.

It might be noted that this years LS1 is now making 300 lb/ft of torque at ! 1000 RPM! I don't think the L98 could muster that.
It just generates a bunch of torque in that sweet spot around 3200 where the resonant frequency of the runners comes into play. Then, right after that, it all disappears...
