Nice, thanks for the pictures. I had a guy tell me the only way to know is pull the heads. By the power that this car has I'm pretty certain it's the commando motor. All I have to do is pull a plug!
I've had this car for 6 years and it's a blast to drive. I get asked quite often is it a hemi!
I've been trying to figure out how rare my car is, it's a 65 dart, 270 convertible. 273, which I believe is the commando motor with a 4 speed. I've taken it to shows and no one has ever seen on like it?
