You are right that a 4.6 would need an alot of very expensive work to put down that kind of hp. I think the dyno test was very high for a 4.6. That's why I brought up my ss camaro dyno. There are lot's of 4.6 cobras I've run against, none stock. I lost to one that had gears, blower and too many add ons to list. I considider my pantera quick, and enjoy the car every time i get into it. I just read about all these different dyno numbers and it makes me curious as to why such a difference.
