Quote: From all I've gathered on the d-dart spec's and numbers, they were for race-only application purchases from dodge.
The cam and holley were installed in a 10.5:1 compression 273, with the single plane intake and dual point ignition. it was only a special option in '66.
There isnt anyone out there that I've found that has a Spec or can grind a D-Dart Cam. I contact a number of custom grinders, and a few of them even told me that if I found one in an old race car to let them know and they'd pay for me to send it to them so they could duplicate it.
I have yet to see a car with the d-dart package confirmed installed on the car. So if you are lucky enough to find one, snag it.
I got one ground for my 64.
if you have any questions regarding the D/Dart you should talk with ddartdude@aol.com. he's owned several D/Darts and know several who raced them back in the day.
As far as heads, I'll stick to my 920s. We can get some pretty good flow numbers out of them.
