What is a good American vehicle to make fast/build?

Looking around for a new car that would make a decent daily driver while still being a good mod platform for speed/acceleration.

Budget is $20k-$25k. I'm looking at a few Ford 6.4 Powerstrokes, Ford Mustang GT 4.6/5.0, Camaro SS 6.2, Silverado 6.6 duramax.

Any other suggestions? I'm not looking to do full on engine builds, just bolt-on mods(preferably kits).

FIRST YOU NEED TO MAKE UP YOUR MIND, TRUCK? OR CAR!
THE TRUCKS WEIGH TWICE AS MUCH.

No diesel engines at ll. They are not meant for speed but durability. Plus they reek of diesel and annoy the people around you.

You can't beat a Mustang, Challenger or Camaro.
