And if you've never heard a well built 273 singing it's song at high RPM, you're in for a treat. It's distinctive, and addictive.
I've got one under the bench and collecting parts, waiting it's turn for a build, just because I want to. Don't even know what I'd put it in; although I've been considering a "Track T" type build for a few years now- hinging on finding suitable vintage Mopar sheet metal that won't bankrupt me. My wife says I'm getting too old to climb into a T bucket anymore...
