I don't think those curves are bizarre at all using the stock cam.. if you look at the stock curves, they are fairly similar to oink's power peaks and distribution. If someone has some time and knowledge, and oink posts the pics of his dyno run, I bet the shape and distribution of a stock sn95 and his freak will be similar. (but his curves will be waaaaaay higher.)
If you keep running that rich, with that much trq, you'll be picking up 2 new tires with ever fill up.
Nice car, too.
