Curious to know what your goals are with your rides. I was forced into selecting the Impala because of my size. I just plain don't fit into a Camaro. Doesn't mean I don't want a hot rod, so I used an old axiom, "If you apply enough power you can get a brick to fly" (McDonald-Grumman Corp when building the Phantom II F-4 fighter-bomber). I replaced my SBC with a big BBC; instant hot rod. Of course I had to beef a few things up like the brakes and suspension, but I followed GM’s lead and used pick-up truck parts to make everything heavy duty.
