What PARTS did Hurst and Chrysler put in the Super Stock Barracuda & Dart not in other factory cars

think you mean just race 426 hemi , the standard 426 hemi was an option in the other bodies , but the a body did not . and the other body types were offer the race 426 hemi option also .
You're right, of course. Don't know what I was thinking. But it still hadn't been mentioned. Then again, EVERY single time I take my 69 340 Barracuda to a show or cruise night, somebody tells me their uncle used to have one, but his had a hemi.
