67 Dart 273 swap to 383

Anything is possible says mr sawzall. The cool factor is over the top. Just be aware it won’t handle nimble like your 273.
alloy heads, alloy intake, Dcr around 9.0 or better, alloy wheels, battery-in-trunk, bigger T-bars and springs, Rally shocks all 'round, and a Double-Pumper will make it all better.
with factory tubs barely allowing 255s, on the street, you might as well put a 2bbl on it, at least until you get the traction issues sorted..
I've only ever passengered in two different 383 4bbl cars, and I will never forget either of them.
