Do you know for fact that the stock cams are still in your motor?

If I had to guess, I'd doubt it with that horsepower curve. I've used a high backpressure HFS and it's makes more heat than horsepower on a stock or near stock motor.

There is no way of knowing for sure what cams are in there until you remove them.
