Yep. Grocery getters, socrer mom SUVs, and economy shitboxes from today are every bit as fast as the performance model muscle cars 50 years ago. Thats what progress and innovation look like.
You can get a 73 car to go that fast and handle as well as a current muscle car. The recipe is gonna look something like
Replace your engine and transmission with something newer.
Swap over to fuel injection.
Replace your suspension with coil overs and IRS.
Enough brakes to stop all that power.
Basically replace everything thing besides the body and interior.
Quickest path these days is an LS swap, with boost. Yes, you can even LS swap old fords if you hold your nose while doing it. Whipple or a pair of angry snails, dyno tune, and you're set.
