Hot Rod Magazine HP 273 build
I don't get the magazine but just caught this. Looks like their dyno numbers were damn close to the factory's 235 horse rating. They added headers and dyno'd it again for a slight increase. There's some D Dart info at the end of the article.
@ddartdude Alan,have you seen this yet?
