The problem with the 300-H is that there is nothing great about it. Many found a nice 300 with a 375hp, found a fiberglass hood and deck and Presto! They got a 300 Hurst.
Chrysler (for some odd reason) thought they were going to make these for 1971. So Hurst made 1000 extra hoods and decks. There's a lot of clones out there but who cares? Done right, there's no difference.
Car was way too expensive in 1970 and nothing like the car show prototype which had a six pack, upgraded suspension, moonroof and hurst shifter. I believe its the only car Hurst did that doesn't have a hurst shifter.
When I was kid in the 70's, 300 Hurst was considered a beautiful car, but somewhat of a joke, clown car. However it was the first car I know of that uses a bunch of stripes, paint, goofy visual things to make a car look faster than it was. Many car companies did the same thing after that.
