Hello new here 64 dart gt
Welcome.. From time to time you see them on Ebay the get big $$$
man a 440 is a heck of a feat in an early A, Major work but can be done. I stroker 383 fots much better still a lot of work though!
Is it going to be an auto or stick and are you going to sub-frame, mini tube etc the car?
I have had my dart 64 GT since 74, I run a stroker 416 was a 340, easy fit and makes as much if not more power that most 440s until of course you mod them too :)
