Building the car no one wants

Yea, when I push my 318's pedal to the floor (two barrel), it seems to me to really move out now. I almost feel as if I have to hang on to something. It's an automatic with a 2.76 gear out back. It used to be a four-speed and a 4.56 ring and pinion that got my adrenaline flowing. Turning 60 this month, must be getting old or somethin'.
