Interesting thread. How much do you drive the car and where? Freeway? Just to cruise nights? Sounds like a bit much on the cam side to me. I've also heard the 3.54 gear wasn't a great performer down low for cars not set up to overcome the gear. I think changing tires to the 295/60 will help the pep, but I don't think you will like it if you drive it any significant distances.
