273 or 225?
@tandart66 can you clarify what rebuild your 66 dart means? Are you doing a full restoration, or focusing on certain areas as issues present themselves?
I replaced the 225 in my 65 dart with a 273 last year. After 4 years of collecting parts. Still didn’t drive much this year because of life stuff, but also some mechanical things that I want to address (rebuilding transmission like I should have in the first place, focusing on suspension and steering, and replacing rotted floors, etc.). The answer to the questions above may help folks respond too.
