The link is not working now?
Personally, I'm thinking it's a freak... Those car guys that are on Sunday mornings on TNN or whatever ran a LS1 on an engine dyno, and pulled close to 400hp with a cam and an LSX intake. Maybe more mods, but I forget. It was running big long headers too, and I don't recall seeing any accessories.
One thing I'm curious about - Why the heck don't these motors put down more torque when modded? At the peaks you see a jump of 74hp, but only 24ft/lbs?
Is it because the HP is just coming from the extended rev's of the motor?
