Lastly, the 20tq gap from the 481tq peak of the ls7 to the 500 line is much larger than the gap from the 400 line to the gt350's 429tq. It should be the other way because 19 is a smaller number than 29 so the gaps should be noticeably reflective of that difference. The major issue is that ford opted to release a useless graph with a 600 tq value and 550hp. On fords graph hp and torque cross in the 45-4800rpm range iirc.

Lastly, the gt350 makes nearly peak power well into 8,000rpms as the ford dyno release showed. In the graph listed here, it falls off far worse than it should from 7500rpm.

The ls7 is great but I would like to see Chevy revise it to about 550hp. It has the potential and would help Chevy continue to command an ls7 premium. As it sits, the 455-460hp 6.2 is too close to the ls7's output to command a typical $25-40k premium. Many have argued the majority of the z28's $75k price (advertised as the cost of the vehicle) is because an ls7 is a $20k+ crate engine. I wonder what a z28 with a 460hp 6.2 would really leave on the table vs an ls7 z28. Price wise it would likely have left $15-20k in a buyers pocket.

I dunno the suspension is also fairly pricey as are the brakes, wheels and tires so those probably jack the price up decently. The engine will certainly be cause for a lot of the price increase though for sure.
