Just did this mock up using GM's engine dyno chart and the Voodoo dyno chart that someone took a picture of. Numbers aren't perfect and are an estimate in some areas but should be pretty close.
While the initial numbers of the Voodoo look pretty good, it's the area under the curve that tell the whole story and it looks like the LS7 is a much more stout engine with the power. A lot less spiky and more predictable..
